Under FreeBSD, as annoying as it is, switches must directly follow the
command or subcommand in question, and cannot come after actual payload
argument. Calling `zpool get all -H` instead of `zpool get -H all`
caused error messages to be spewed to the console under FreeBSD when
simply completing `zfs <TAB>`, this should fix that. The change should
also be compatible with other operating systems (namely Linux) that
don't have this requirement, as they (generally) allow arguments to come
before _or_ after the primary non-switch argument (though I do not have
access to a zfs-enabled Linux machine to test this).
Previously, trying to complete a token with any of these
expansion-related characters would cause the completion to return no
results, as it would emit expanded values which weren't matched by the
autocompleter.
Only the first non-switch parameter to python must be a .py file, but
everything thereafter is "just another argument". This enables file
completions for 2nd+ arguments.
Akin to __fish_complete_suffix, __fish_complete_directories now attempts
to complete the current commandline token if no token is explicitly
passed in as an argument.
The prompt is a fallback that is overridden via a function file
anyway.
Do that with the title as well, so we can use just builtins.
This removes error messages when $fish_function_path is borked.
Turns out that `make -pn` actually takes a while - about 300ms on
fish's makefile.
That's quite a bit of time just to throw away the output and use the
exit code.
So we just check for "GNU" in the version string.
It would be nice to just _do_ the completion and fall back on the
BSD-style if it doesn't work, but that is tricky to do with the pipe
to `awk` - the awk expression actually does not fail if `make` does
not print output.
And I don't know enough about awk to change that.
While this is a bit faster (mostly because it needs less processing on fish's side),
it lacks the neat description bit and the ":/" stuff doesn't work.
The boost is also not large in absolute terms (a few milliseconds).
This reverts commit 1f8e4dad9f.
This uses the same logic that git uses to determine the satus of files
and doesn't require any parsing on our end. Brings in support for
relative paths (such as `git add ../f<TAB>`). Should be faster and more
reliable than manually parsing porcelain status.
This doesn't support as many cases as the old `__git_ls_files` function
did (e.g. `renamed` is not supported, nor is `added`), both of which
_can_ be implemented on top of the new logic - but neither of which were
actually being used, anyway.
Usefulness is decreased by #4970, speed still bottlenecked by #4969.

This is based on what the official git completions do, and it's quite
fast.
Also only complete files after a "--" separator for `checkout`.
Fixes#4858.
This is much quicker - on the order of 100ms vs 50ms.
We shorten to 10 characters, which is statistically suitable - 3 out
of 600k commits in the linux kernel need 11 characters.
For usage in completion scripts.
Unlike `__fish_is_first_token` (which is probably not correctly named),
`__fish_is_first_arg` returns true regardless of whether existing tokens start with `-`
or not, to be used when an arg cannot be used with any other argument.
`__fish_prev_arg_in` is similar to `__fish_seen_...` but it explicitly
tests the preceding token only, for arguments that take only a single
parameter.
As it turns out, for some terminals backspace is \b but only when
preceded by \e.
All this makes about as much sense as the english language.
Fixes#4955.
