Unfortunately, there's no standard way to detect support (importantly,
terminfo doesn't encode it), but there's a variety of terminals that
support it that we can detect.
It's better than letting this functionality go to waste.
Check KONSOLE_PROFILE_NAME instead of DBUS_SESSION because Konsole can be compiled without dbus support.
Check ITERM_SESSION_ID's format for 24bit support
This has changed since the last release, just like 24bit support. So if
we check one, we get the other.
Allows the length of each shortened path component to be customized by setting the `fish_prompt_pwd_dir_length` variable to the number of characters to include (plus a leading dot because that's special). Maintains the default behavior of shortening path components to just one character. You can also set `fish_prompt_pwd_dir_length` to an empty or invalid value or 0 to disable shortening completely.
This reduces code duplication and adds some previously unavailable
bindings that don't quite _violate_ the vi-principle (like
prevd-or-backward-word on alt-left) and matches other "impure" bindings
like \cf for forward-word (a quite emacs-ish binding) we already have.

For cygwin, you can't `cd C:`, so a prompt of "C:/Something" is
misleading.
For OSX, we dereference symlinks elsewhere
This also simplifies prompt_pwd quite a bit.
This is to the benefit of systems with ancient GNU sed, which does not
recognize "-E", but only "-r".
Fixes#2305 - even if it doesn't replace all `sed -E` invocations in the
codebase, the others are unlikely to occur on CentOS and other similarly
crusty systems.
`sort -u | uniq` is completely redundant, calling grep for every
status-pair is unnecessary, `contains` doesn't take the word "in" as
special.
None of these are critical and there's basically no performance benefit
since this function is utterly dominated by hg calls.
This doesn't add anything except slowing the function down by about
33%. Checking for a branch is just as good and that is displayed in the
prompt anyway.
This is used in at least 4 places, all of which have a bug in that they
print "options" as a valid repo. It seems better to fix it once,
especially given that there are tons of AUR helpers and pacman wrappers,
all of which might need this info.
net_tools, which provides `ifconfig` and `netstat`, among other things,
has last been updated in 2013. This means `ifconfig` on linux is
basically dead.
Instead of ifconfig, use `ip` (from iproute2), which is much more powerful and
provides a much more annoying commandline syntax.
Instead of netstat, just look at /sys/class/net.
