If we're at the beginning of the commandline, we trim leading whitespace so we don't trigger histignore.
Since that's the main issue of problems with histignore:
Closes#4327.
C++11 provides std::min/std::max which we're using all over,
obviating the need for our own templates for this.
util.h now only provides two things: get_time and wcsfilecmp.
This commit removes everything that includes it which doesn't
use either; most because they no longer need mini or maxi from
it but some others were #including it unnecessarily.
Hangul uses three codepoints to combine to one glyph. The first has a
width of 2 (like the final glyph), but the second and third were
assigned a width of 1, which seems to match EastAsianWidth.txt:
> 1160..11FF;N # Lo [160] HANGUL JUNGSEONG FILLER..HANGUL JONGSEONG SSANGNIEUN
Instead, we override that and treat the middle and end codepoint as combiners,
always, because there's no way to figure out what the terminal will
think and that's the way it's supposed to work.
If they stand by themselves or in another combination, they'll indeed
show up with a width of 1 so we'll get it wrong, but that's less
likely and not expressible with wcwidth().
Fixes#5729.
This only did prefix matching, which is generally less useful.
All existing users _should_ be okay with this since they want to
provide completions.
Fixes#5467.
Fixes#2318.

That tried to fix problems with pkgconfig by not recreating it.
Instead, use the function we already have for not trying too hard to
create a directory.
Fixes#5735.
This addresses a few places where -Wswitch-enum showed one or two missing
case's for enum values.
It did uncover and fix one apparent oversight:
$ function asd -p 100
echo foo
end
$ functions --handlers-type exit
Event exit
asd
It looks like this should be showing a PID before 'asd' just like
job_exit handlers show the job id. It was falling
through to default: which just printed the function name.
$ functions --handlers-type exit
Event exit
100 asd
Also prevents file completions where they are not approprite, and
additionally shortened the descriptions to fit in two pager columns
in an 80-wide terminal for some platforms.
Apparently if you install gnu coreutils on OpenBSD, the tools are
g-prefixed. So we definitely want to just alias that rather than
provide our lousy shell script implementation.
Apparently that's actually faster than jq, and it's more likely to be
installed.
Also it should convince the arch packager to remove the jq dependency.
The indentation is weird, though.

+ tweaks for Linux: shorter descriptions, suppress file completions
+ Add correct completions for macOS, NetBSD, FreeBSD, OpenBSD, DragonFly
+ Solaris dmesg has no options, so complete nothing there
25d83ed0d7 (included in 3.0.0) added a `string` check that
did not use `--`, so negative numbers were interpreted as options.
Apparently nobody is using this.
(Again, this is for the `seq` fallback used on OpenBSD)
This tried to skip conversion if the locale had MB_CUR_MAX == 1, but
in doing so it just entered an infinite recursion (because
writestr(wchar_t*) called writestr(wchar_t*)).
Instead, just let wcstombs handle it.
Fixes#5724.
Since Unicode 9, the width of some characters changed to 2.
Depending on the system, it might have support for it, or it might
not.
Instead of hardcoding specific glibc etc versions, we check what the
system wcwidth says to "😃", U+1F603 "Grinning Face With Big Eyes".
The intention is to, in most cases, make setting $fish_emoji_width
unnecessary, but since it sets the "guessed_emoji_width", that variable still takes precedence if it is set.
Unfortunately this approach has some caveats:
- It relies on the locale being set to a unicode-supporting one.
(C.UTF-8 is unfortunately not standard, so we can't use it)
- It relies on the terminal's wcwidth having unicode9 support IFF the
system wcwidth does.
This is like #5722, but at runtime.
The additional caveat is that we don't try to achieve a unicode
locale, but since we re-run the heuristic when the locale changes (and
we try to get a unicode locale), we should still often get the correct
value.
Plus if you use a C locale and your terminal still displays emoji,
you've misconfigured your system.
Fixes#5722.
These aren't perfect, but the tool is pretty much hostile to proper
completions - it includes a "--machine-readable" option, but `vagrant
global-status --machine-readable` prints great output like

and still takes 500ms to do so. The actual information is in a json
file, which we can't expect to read, and it doesn't have linebreaks or
such which we could use to hack-parse it.
So this is the best we can do for the most important bits (the
machineids), so let's just add this as-is.
