Add set --function (#8145)
* Add `set --function`

This makes the function's scope available, even inside of blocks. Outside of blocks it's the toplevel local scope.

This removes the need to declare variables locally before use, and will probably end up being the main way variables get set.

E.g.:

```fish
set -l thing
if condition
    set thing one
else
    set thing two
end
```

could be written as

```fish
if condition
    set -f thing one
else
    set -f thing two
end
```

Note: Many scripts shipped with fish use workarounds like `and`/`or`
instead of `if`, so it isn't easy to find good examples.

Also, if there isn't an else-branch in that above, just with

```fish
if condition
    set -f thing one
end
```

that means something different from setting it before! Now, if
`condition` isn't true, it would use a global (or universal) variable of
te same name!

Some more interesting parts:

Because it *is* a local scope, setting a variable `-f` and
`-l` in the toplevel of a function ends up the same:

```fish
function foo2
    set -l foo bar
    set -f foo baz # modifies the *same* variable!
end
```

but setting it locally inside a block creates a new local variable
that shadows the function-scoped variable:

```fish
function foo3
    set -f foo bar
    begin
        set -l foo banana
        # $foo is banana
    end
    # $foo is bar again
end
```

This is how local variables already work. "Local" is actually "block-scoped".

Also `set --show` will only show the closest local scope, so it won't
show a shadowed function-level variable. Again, this is how local
variables already work, and could be done as a separate change.

As a fun tidbit, functions with --no-scope-shadowing can now use this to set variables in the calling function. That's probably okay given that it's already an escape hatch (but to be clear: if it turns out to problematic I reserve the right to remove it).

Fixes #565

Let "return" exit a script (#8148)
Currently, if a "return" is given outside of a function, we'd just
throw an error.

That always struck me as a bit weird, given that scripts can also
return a value.

So simply let "return" outside also exit the script, kinda like "exit"
does.

However, unlike "exit" it doesn't quit an interactive shell - it seems
weird to have "return" do that as well. It sets $status, so it can be
used to quickly set that, in case you want to test something.

8223e6f23e fish_config: Add CLI-based theme selector
`fish_config theme`:

- `list` to list all available themes (files in the two theme
directories - either the web_config/themes one or
~/.config/fish/themes!)
- `show` to show select (or all) themes right in the terminal - this
starts another fish that reads the theme file and prints the sample
text, manually colored
- `choose` to load a theme *now*, setting the variables globally
- `save` to load a theme and save the variables universally
- `dump` to write the current theme in .theme format (to stdout)
- `demo` to display the current theme

string: Allow collect --allow-empty to avoid empty ellision (#8054)
* string: Allow `collect --no-empty` to avoid empty ellision

Currently we still have that issue where

    test -n (thing | string collect)

can return true if `thing` doesn't print anything, because the
collected argument will still be removed.

So, what we do is allow `--no-empty` to be used, in which case we
print one empty argument.

This means

    test -n (thing | string collect -n)

can now be safely used.

"no-empty" isn't the best name for this flag, but string's design
really incentivizes reusing names, and it's not *terrible*.

* Switch to `--allow-empty`

`--no-empty` does the exact opposite for `string split` and split0.

Since `-a`/`--allow-empty` already exists, use it.

33f3c03dae Allow on-job-exit handlers to be added for any pid in the job
Prior to this change, a function with an on-job-exit event handler must be
added with the pgid of the job. But sometimes the pgid of the job is fish
itself (if job control is disabled) and the previous commit made last_pid
an actual pid from the job, instead of its pgroup.

Switch on-job-exit to accept any pid from the job (except fish itself).
This allows it to be used directly with $last_pid, except that it now
works if job control is off. This is implemented by "resolving" the pid to
the internal job id at the point the event handler is added.

Also switch to passing the last pid of the job, rather than its pgroup.
This aligns better with $last_pid.

2b74affaf0 Add prompt selector
It's a bit weird to *have* to fire up a browser to get fish_config to
choose a prompt.

So this adds a `prompt` subcommand to `fish_config`:

- `fish_config prompt list` shows all the available prompt names
- `fish_config prompt show` demos the available sample prompts
- `fish_config prompt choose` sources a prompt
- `fish_config prompt save` makes the choice permanent

A bare `fish_config` or `fish_config browse` opens the web UI.

Part of #3625.

TODO: This shows the right prompt on a new line. Showing it in-line is awkward
to do because we'd have to move it to the right.

math: Make function parentheses optional (#7877)
* math: Make function parentheses optional

It's a bit annoying to use parentheses here because that requires
quoting or escaping.

This allows the parens to be omitted, so

math sin pi

is the same as

math 'sin(pi)'

Function calls have the lowest precedence, so

math sin 2 + 6

is the same as

math 'sin(2 + 6)'

5a0aa7824f Saturate exit codes to 255 for all builtins
After commit 6dd6a57c60, 3 remaining
builtins were affected by uint8_t overflow: `exit`, `return`, and
`functions --query`.

This commit:
- Moves the overflow check from `builtin_set_query` to `builtin_run`.
- Removes a conflicting int -> uint8_t conversion in `builtin_return`.
- Adds tests for the 3 remaining affected builtins.
- Simplifies the wording for the documentation for `set --query`.
- Does not change documentation for `functions --query`, because it does
  not state the exit code in its API.
- Updates the CHANGELOG to reflect the change to all builtins.

6dd6a57c60 Saturate return value in builtin_set_query
builtin_set_query returns the number of missing variables. Because the
return value passed to the shell is an 8-bit unsigned integer, if the
number of missing variables is a multiple of 256, it would overflow to 0.

This commit saturates the return value at 255 if there are more than 255
missing variables.

6eeb8861e7 Add exit bind function
Currently binding `exit` to a key checks too late that it's exitted,
so it leaves the shell hanging around until the user does an execute
or similar.

As I understand it, the `exit` builtin is supposed to only exit the
current "thread" (once that actually becomes a thing), and the
bindings would probably run in a dedicated one, so the simplest
solution here is to just add an `exit` bind function.

argparse: Make short flag names optional (#7585)
It was always a bit ridiculous that argparse required `X-longflag` if
that "X" short flag was never actually used anywhere.

Since the short letter is for getopt's benefit, we can hack around
this with our old friend: Unicode Private Use Areas.

We have a counter, starting at 0xE000 and going to 0xF8FF, that counts
up for all options that don't have a short flag and provides one. This
gives us up to 6400 long-only options.

6.4K should be enough for everybody.

f758d39535 string pad: handle padding characters of width > 1
If the padding is not divisible by the char's width without remainder,
we pad the remainder with spaces, so the total width of the output is correct.

Also add completions, changelog entry, adjust documentation, add examples
with emoji and some tests.  Apply some minor style nitpicks and avoid extra
allocations of the input strings.

0072367512 fish_add_path: Don't resolve symlinks
The case for symlinked directories being duplicated a lot isn't there,
but there *is* a usecase for adding the symlink rather than the
target, and that's homebrew.

E.g. homebrew installs ruby into /usr/local/Cellar/ruby/2.7.1_2/bin,
and links to it from /usr/local/opt/ruby/bin. If we add the target, we
would miss updates.

Having path entries that point to the same location isn't a big
problem - it's a path lookup, so it takes a teensy bit longer. The
canonicalization is mainly so paths don't end up duplicated via weird
spelling and so relative paths can be used.

903b7888d3 complete: Make -c optional
Currently, completions have to be specified like

```fish
complete -c foo -l opt
```

while

```fish
complete foo -l opt
```

just complains about there being too many arguments.

That's kinda useless, so we just assume if there is one left-over
argument that it's meant to be the command.

Theoretically we could also use *all* the arguments as commands to
complete, but that seems unlikely to be what the user wants.

(I don't think multi-command completions really happen)

So just make `complete -c foo` list all the completions for `foo`.

340de73172 Call "fish_command_not_found" if a command wasn't found
Previously, when a command wasn't found, fish would emit the
"fish_command_not_found" *event*.

This was annoying as it was hard to override (the code ended up
checking for a function called `__fish_command_not_found_handler`
anyway!), the setup was ugly,
and it's useless - there is no use case for multiple command-not-found handlers.

Instead, let's just call a function `fish_command_not_found` if it
exists, or print the default message otherwise.

The event is completely removed, but because a missing event is not an error
(MEISNAE in C++-speak) this isn't an issue.

Note that, for backwards-compatibility, we still keep the default
handler function around even tho the new one is hard-coded in C++.

Also, if we detect a previous handler, the new handler just calls it.

This way, the backwards-compatible way to install a custom handler is:

```fish
function __fish_command_not_found_handler --on-event fish_command_not_found
    # do a little dance, make a little love, get down tonight
end
```

and the new hotness is

```fish
function fish_command_not_found
    # do the thing
end
```

Add an "_" builtin to call into gettext (#7036)
* Add an "_" builtin to call into gettext

We already have gettext in C++ (if available), so it seems weird to
fork off a command to start it from script.

This is only for fish's own translations. There's no way to call into
other catalogs, it just translates all arguments separately.

This is faster by a factor of ~1000, which allows us to call
translations much more, especially from scripts.

E.g. making fish_greeting global by default would hurt cost-wise,
given that my fish starts up in 8ms and just calling the current `_`
function takes 2ms, and that would have two calls.

Incidentally, this also makes us rely on a weirdly defined function
less, so it:

9354dd6971 Add fish_add_path, a simple way to add to $PATH
This is a function you can either execute once, interactively, or
stick in config.fish, and it will do the right thing.

Some options are included to choose some slightly different behavior,
like setting $PATH directly instead of $fish_user_paths, or moving
already existing components to the front/back instead of ignoring
them, or appending new components instead of prepending them.

The defaults were chosen because they are the most safe, and
especially because they allow it to be idempotent - running it again
and again and again won't change anything, it won't even run the
actual `set` because it skips that if all components are already in.

2e4cb15880 Add self-insert-notfirst readline command
This adds a new readline command self-insert-notfirst, which is
analogous to self-insert, except that it does nothing if the cursor
is at the beginning. This will serve as a higher-performance implementation
for stripping leading spaces on paste.

da7b762f4a Make default hg prompt leaner
The default hg prompt is slow on large repositories (hg status takes
2-3 seconds on mozilla-central) which is unacceptable as a default.

Mimick our git prompt: by default, only show the current branch.
If the new variable $fish_prompt_hg_show_informative_status is set,
then use the old behavior.

bfc1de9ef4 argparse: Pass validation variables as exported
This was written before local-exported variables did anything useful.

Passing these vars as local-exports removes the need to define the
validation function with `--no-scope-shadowing` which is quite the
hack.

0f34459fce Disable svn prompt by default
This is apparently quite slow on large svn repos (like 40 seconds
slow), and we don't have a good thing to display other than the full
file information.

So we'll have to disable it for now.

Fixes #6681.
