This runs in 100ms increments, so there's not a lot of harm in trying
longer - it should take the same time everywhere it succeeded before.
But I've reproduced failures on FreeBSD 13 on sr.ht, so there's at
least one platform where a total time of 1 second isn't enough.
Now we do 50 tries, which is 5 seconds.
This could have been one iteration off, e.g.
```fish
function on-winch --on-signal winch
echo $LINES
end
```
Resize the terminal, it'll print e.g.
24
then run `echo $LINES` interactively, it might have a different answer.
This isn't beautiful, but it works. A better solution might be to make
the termsize vars electric and just always update them on read?
Fixes#7926.
Also switches the default status order for non-informative to the informative one:
stagedstate invalidstate dirtystate untrackedfiles stashstate
instead of
dirty staged stash untracked
With something like
```
history | head -n 1
```
this would error "write: Broken pipe", which is just annoying. There
is no *problem* here, `head` closes this on purpose.
Fixes#7924.
Things like
```fish
complete command -n '__fish_seen_subcommand_from subcommand'
--force-files
```
would not be obeyed because we only checked force-files when there was
an option.
Fixes#7920.
When a terminal in a tiling WM starts, it might start the shell before
it has reached its "final" size. So we get the terminal width,
then the terminal would be resized (to appease the tiling logic),
and then we would print the abandon line with the omitted newline
char, only if the size got smaller (likely!), we would overflow the
line and land on the next.
So what we do is a bit of a hack: We don't abandon the first line.
This means that `printf %s foo; fish` will overwrite the `foo`, but
that's a super small problem and I don't see another way around this.
Fixes#7893.
This isn't helpful, and entirely unreadable. Excerpt:
```
__fish_git_prompt_set_char (set -l user_variable_name "$argv[1]" set -l char $argv[2] if set -q argv[3] and begin set -q __fish_git_prompt_show_informative_status or set -q __fi…)
```

This should be a simple prompt that doesn't place a huge strain on the
system but communicates the most important information simply and
effectively.
It should be a good jumping off point for making your own prompt.
Unless that person directly contributed the prompt.
We name them after a feature - the Scales prompt feature a ">>>" which
kinda looks like fish scales, the "Arrow" prompt starts with a
prominent "➜".
Naming them after people looks like an endorsement of that particular
person, and like they are someone to look up to, especially when they
aren't involved with the project.
The "terlar" and "acidhub" prompts stay for now because they
contributed the prompt themselves, they are also much less prominent.
The "classic" prompts are all just variations on a theme, let's just
keep the default classic+vcs.
"Justadollar" is very unlikely to be what you want and also trivial to
write yourself.
I have no idea what screen_savvy even is for - it reacts to "$WINDOW",
but I don't know anything that even uses that variable.
Lonetwin is just unremarkable, and the debian chroot prompt has one special feature that should be integrated into the other prompts.
When fish starts, it notices which pgroup owns the tty, and then it
restores that pgroup's tty ownership when it exits. However if fish does
not own the tty, then (on Mac at least) the tcsetpgrp call triggers a
SIGSTOP and fish will hang while trying to exit.
The first change is to ignore SIGTTOU instead of defaulting it. This
prevents the hang; however it risks re-introducing #7060.
The second change somewhat mitigates the risk of the first: only do the
restore if the initial pgroup is different than fish's pgroup. This
prevents some useless calls which might potentially steal the tty from
another process (e.g. in #7060).

If fish launches a program and that program marks stdin as O_ASYNC, then
fish will start receiving SIGIO events on Mac. This occurs even though
the file descriptor itself does not have the O_ASYNC flag set.
SIGIO is reported as interrupting select which then breaks multiple-key
bindings, especially in vi-mode.
As the SIGIO based universal notifier is disabled, remove it and the
SIGIO handler itself. This allows fish to ignore properly ignore SIGIO.

This correctly sets $status when a builtin succeeds but its output fails;
for example if the output is redirected to a file and that write fails.
Fixes#7857
Because macOS' `apropos` is just using grep, and we only need
a prefix match for __fish_describe_command, we can shave off
some ok total execution time here.
