0ae6d34845 docs: Make lAtEX output *work*
pdflatex simply doesn't cut it.

This still results in an awkward pdf that starts with "Further
Reading" (the intro section is placed before it, but doesn't have a
chapter marker!) and ends with a massive "Other help pages" chapter
that includes *the entire rest of the docs*.

But it's generally readable and acceptably formatted (with a lot of
empty pages in between).

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.

670636885c docs: Made the abort/edit history feature more discoverable.
First, I changed "the escape key" to :kbd:`Esc`. This makes this information
easier to find when scanning the docs because it stands out and because it is
more consistent with the docs's formatting of keyboard keys.

Additionally, emphasize that escape/page-down can be used to edit
the original search sting.

Finally, I added a link from the FAQ to history-search to make this mechanism
easier to discover.

This was all to address confusion in former zsh and bash users as to how to
edit a search that is in progress, but this will also help new users. See

Try to set LC_CTYPE to something UTF-8 capable (#8031)
* Try to set LC_CTYPE to something UTF-8 capable

When fish is started with LC_CTYPE=C (even just effectively, often via
LC_ALL=C!), it's basically broken. There's no way to handle non-ASCII
characters with a C locale unless we want to write our
locale-independent replacements for all of the system functions.

Since we're not going to do that, let's try to find *some locale* for
LC_CTYPE.

We already do that in __fish_setlocale, but that's

- a bit of a weird thing that reads unstandardized system
  configuration files
- allows setting locale to C explicitly

So it's still easily possible to end up in a broken configuration.

Now, the issue with this is that there is (AFAICT) no portable way to
get a list of all allowed locales and C.UTF-8 is not standardized, so
we have no one locale to fall back on and are forced to try a few. The
list we have here is quite arbitrary, but it's a start.

Python does something similar and only tries C.UTF-8, C.utf8 and
"UTF-8".

Once C.UTF-8 is (hopefully) standardized, that will just start
working (tm).

Note that we do not *export* the fixed LC_CTYPE variable, so external
programs still have to deal with the C locale, but we have no real
business messing with the user's environment.

To turn it off: $fish_allow_singlebyte_locale, if set to something true (like "1"),
will re-run the locale initialization and skip the bit where we force
LC_CTYPE to be utf8-capable.

This is mainly used in our tests, but might also be useful if people
are trying to do something weird.

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

58885fbd0b docs: Handle undefined LINK_SUFFIX
When building the docs with an old sphinx (like e.g. on Debian), this
would break links in the search results.

This happens because we've nabbed the searchtools.js from a sphinx to
add our special handling of short builtins like "and", "end", "cd" (as
part of #7757).

I don't believe this will change *a lot* in practice, so it's probably
still okay, but this hack is still worthwhile.

18e332772d functions: Add "--no-details" flag and use it in funced
This inhibits the function path comment which is annoying in `funced`.

Fixes #7879.

e1d19cf571 Don't touch $SHLVL if not interactive
It's not super clear what $SHLVL is useful for, but the current
definition is essentially
"number of shells in the parent processes + 1"

which isn't *super useful*?

Bash's behavior here is a bit weird in that it increments $SHLVL
basically always, but since it auto-execs the last process it will
decrement it again, so in practice it's often not incremented.

E.g.

```
> echo $SHLVL
1
> bash -c 'echo $SHLVL; bash'
2
>> echo $SHLVL
2
```

Both bashes here end up having the same $SHLVL because this is
equivalent to `echo $SHLVL; exec bash`. Running `echo $SHLVL` and then
`bash -c 'echo $SHLVL'` in an interactive bash will have a different
result (1 and 2) because that doesn't *exec* the inner bash.

That's not something we want to get into, so what we do is increment
$SHLVL in every interactive fish. Non-interactive fish will simply
import the existing value.

That means if you had e.g. a bash that runs a fish script that ends up
opening a new fish session, you would have a $SHLVL of *2* - one for the
bash, and one for the inner fish.

We key this off is_interactive_session() (which can also be enabled
via `fish -i`) because it's easy and because `fish -i` is asking for
fish to be, in some form, "interactive".

That means most of the time $SHLVL will be "how many shells am I deep,
how often do I have to `exit`", except for when you specifically asked
for a fish to be "interactive". If that's a problem, we can rethink it.

Fixes #7864.

e7abb52526 Remove special "default" value for $fish_history
This is really of very little use and makes checking $fish_history
harder because it makes two values mean the same thing.

93eaa61294 Split up documentation
This breaks apart the massive "index" document into

1. An "index" document that explains how to install and set up fish
and links to the other documents
2. A "fish-language" document that describes the syntax and semantics
of the language
3. A "fish-interactive" document that describes how to use fish
interactively

No change to the content has been made, only the parts have been moved
from index and some of the formatting (links and header levels) were
fixed.

See #7348.

58177ba091 docs: Replace all internal links with :ref:s
Unlike links, these are checked by sphinx and it complains if they
don't match.

Also they have a better chance of doing something useful in outputs
other than html.

This was a bit stuffy

Also let's mention tmux because that's another thing that may cause this.

c96a07dc96 Revert "Prevent redirecting internal processes to file descriptors above 2"
FDs are inherited, and redirecting those is harmless, and forbidding
that is worse than allowing all.

Fixes #7769.

This reverts commit 11a373f121.
