`ls` was suggesting options that are are not valid for my system,
omitting options that are on my system. Different BSD OSes have
different option extensions, and some of them do conflict with eachother.
I carefully checked the manuals of netbsd, macos, freebsd, and openbsd
`ls` and made the completions show the right completions in full for them.
Some verbiage tweaks as well.
- No longer uses sed, sort, uniq, uname
- Stop doing too-clever filtering (e.g. the kernel thread stuff never
- really worked)
- Don't truncate for all OSen, instead just use the (correctly
- truncated) comm field.
- Colorize history search output when interactive, using
fish_indent. This is the same way we colorize `type` output.
- Ask less to act like `cat` if the output will fit in the
terminal window, so it's less jaring with short output.
- history is viewed in a pager when interactive, but pagers
typically strip escape codes. We accomplish the above by
doing exactly what `git` does[1] when it has colored output
for a pager:
if $LESS is unset, set it to enable -R, -F, and -X options.
if $LV is unset, set it to -c.

Fixes some potentially unsafe uses of direct substitution into regex
expressions and also switches some completions to regex-based now that
there is a safe way of using it.
In writing the completion script for openocd I found the need to
complete paths at the command-line as if they were relative to a
path other than the current $PWD. Given that `$PWD` is currently
global in fish (i.e. no side-effect free `cd` within a subshell)
this is probably good to have for other completions too.
This also fixes a bug in support for explicitly supplying the
description for completions via a `$argv` parameter, which prefixed
the description with `\t` (which is correct) except it did so in
the local scope within an `if` statement, meaning the changes never
had any effect and in the output the description was directly
concatenated to the completions, instead of separated by a tab.
Incorrectly assumed that pandoc uses XDG_CONFIG_HOME, it turns out the
path is hard-coded as $HOME/.pandoc unless explicitly otherwise
specified in the command-line.
Don't attempt to complete against package names if the user is trying to
enter a switch to speed things up.
Also work around #5267 by not wrapping unfiltered `all-the-package-name`
calls in a function.
We do a bunch of escaping before to make `eval` work, and that needs to be removed as well or fragment-urls don't work.
This reverts commit e9568069a7.
Use clang/clang++'s own autocompletion support to complete arguments. It
is rather convoluted as clang generates autocompletions for a portion of
the current token rather than the entire token, e.g. while `--st` will
autocomplete to `--std=` (which is fine by fish), `--std=g` will
autocomplete to `gnu...` without the leading `--std=` which breaks fish'
support for the completion.
Additionally, on systems where clang/clang++ is the system compiler
(such as FreeBSD), it is very often for users to invoke a newer version
of clang/clang++ installed as clang[++]-NN instead of clang. Using a
monkey-patched version of `complete -p` to support that without breaking
(future) completions for commands like `clang-format`.
Closes#4174.
