c0af8dae20 fish_indent: fix extra indent of continuation lines inside blocks
fish_indent used to increment the indentation level whenever we saw an escaped
newline.  This broke because of recent changes to parse_util_compute_indents().
Since parse_util_compute_indents() function already indents continuations
there is not much to do for fish_indent - we can simply query the indentation
level of the newline.  Reshuffle the code since we need to pass the offset
of the newline. Maybe this can even be simplified further.

Fixes #7720

ca4836ff0d Only enable actual flow control on Linux
This fails on FreeBSD on sr.ht and NetBSD on my own VM, but it works manually.

It also fails on macOS but I have no way to confirm.

I think it might be a problem in pexpect's platform support?

Either way, the test is valuable so just skip it there and solve it later.

c27fb9b802 source: Escape filenames in errors
Otherwise this would look weird if you had, say, a tab in there.

See #7716.

(note that this doesn't handle e.g. zero-width-joiners, because those
aren't currently escaped. we might want to add an escape mode for
unprintable characters, but for combining codepoints that's tricky!)

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.

84d59accfc builtins to allow stdin to be closed
Prior to this fix, if stdin were explicitly closed, then builtins would
silently fail. For example:

    count <&-

would just fail with status 1. Remove this limitation and allow each
builtin to handle a closed stdin how it sees fit.

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.

594d51e7eb Add a separate --profile-startup option to profile startup
This goes to a separate file because that makes option parsing easier
and allows profiling both at the same time.

The "normal" profile now contains only the profile data of the actual
run, which is much more useful - you can now profile a function by
running

   fish -C 'source /path/to/thing' --profile /tmp/thefunction.prof -c 'thefunction'

and won't need to filter out extraneous information.

1dd776ec99 echo: Don't interpret and print options
A weird interaction between grouped short options and our weird option
parsing that puts unknown options back:

```
echo "-n foo"
```

would see the `-n`, turn off printing newlines, interpret the " " as
another grouped short option, see that there is no short option for
space and put the entire token back on the arguments pile.

So it would print "-n foo" *without a newline*.

Fix this by keeping an old state of the options around and reverting
it when putting options back.

The alternative is *probably* to forbid the " " short option in
wgetopt, then check if an option group contains it and error out, but
this should only really be a problem in `echo` because that is,
AFAICT, the only thing that puts the options back.

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.

43505f7077 Allow ** glob segments to match zero directories
Prior to this change, a glob like `**/file.txt` would only match
`file.txt` in subdirectories; the `**` must match at least one directory.
This is historical behavior.

With this change we move a little closer to bash's implementation by
allowing a literal `**` segment to match in the current directory. That
is, `**/foo` will match both `foo` and `bar/foo`, while `b**/foo` will
only match `bar/foo`.

e43913a547 Stop expanding globs in command position when performing error checking
Before running a command, or before importing a command from bash history,
we perform error checking. As part of error checking we expand commands
including variables and globs. If the glob is very large, like `/**`, then
we could hang expanding it.

One fix would be to limit the amount of expansion from the glob, but
instead let's just not expand command globs when performing error checking.

In other places it decreases sleeps where we just wait for a timeout to elapse, in which case we don't need much longer than the timeout.

+        return found;
