`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.
The colors happening for the interactive tests didn't match the
expected output. For `history search` commands we test, have them
pipe through `cat` so the fishscript does not use a pager or try
to colorize.
- 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.

If the user is in a directory which has been unlinked, it is possible
for the path .. to not exist, relative to the working directory.
Always pass in the working directory (potentially virtual) to
path_get_cdpath; this ensures we check absolute paths and are immune
from issues if the working directory has been unlinked.
Also introduce a new function path_normalize_for_cd which normalizes the
"join point" of a path and a working directory. This allows us to 'cd' out of
a non-existent directory, but not cd into such a directory.
Fixes#5341
realpath() will return NULL and sets errno if it fails.
We asserted that realpath(".") does not fail. We also didn't really
check that it was successful. Made sure we'll get a perror telling
us about what went wrong if something like this happens again.
Updated tests and added test case
Fixes#5351
* Replace "env" with "expr" in the test manpage
I'm pretty sure `env` isn't capable of comparing numbers and the author meant `expr`.
* Update the docs regarding floats support in test
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.
If fish detects that it was started with a pgrp of 0 (which appears to
oddly be the case when run under firejail), create new process group for
fish and give it control of the terminal.
This selectively reverts 55b3c45 in cases where an invalid pgrp is
detected. Note that this is known to cause problems in other cases, such
as #3805 and Microsoft/WSL#1653, although the former may have been
ameliorated or even addressed by the recent job control overhaul, so
that's why we are careful to only assign fish to its own pgroup if an
invalid pgroup was detected and not as the normal case.
