When the pager wants to use the full screen to show many options, it reserves
space at the top to see the command. Previously it pretended the command was a
prompt and engaged the prompt layout mechanism to compute these lines. Instead
let's juts count newlines since escape sequences within commands are very rare.
This never worked properly (since a branch that only exists locally
would also be offered) and is dog-slow.
When we come up with a better way to do it we can readd it.
When git prints a path like "share/completions/git.fish", that's
relative to the root of the repo. So we need to either remove
everything from the $PWD (if the path is inside the $PWD), or prepend
a ":/", which is git-speak for "relative to the root".
This was removed by mistake in the recent switch to `git status`.
Fixes#4688.
This special cases expansion of $history variables, so that slicing
history no longer needs to construct the entire history array. Speedup
is around 100x in my test.
Fixes#4650
Prior to this fix, if the user typed normal characters while the
completion pager was shown, it would begin searching. This feature was
not well liked, so we are going to instead just append the characters as
normal and disable paging. Control-S can be used to toggle the search
field.
Fixes#2249
CheckFunctionExists checks for C linkage only, and recommends the use of
CheckSymbolExists in the documentation. This improves the detection of
C++ features, as opposed to C features.
try_get_child() was taking the address of a reference; clang was thereby
assuming it could not be null and so was dropping the null check. Ensure
we do not dereference a null pointer.
Fixes#4678
* git completions: Parse git status --porcelain
This is much faster on large repositories, as it allows us to do a lot
more with a single git call.
It also makes it easy to add descriptions to distinguish modified
files from untracked ones.
TBD is if all commands now have the right kinds of files.

`-v` is a non-standard GNU-only extension to `awk`, its usage in the
generation of the fish.pc script breaks on non-GNU platforms (such as
FreeBSD and presumably macOS).
Using `sed` with only standard posix commands instead.
This was a symbol that represented either an argument or a redirection.
This was only used as part of argument_or_redirection_list.
It's simpler to just have these types be alternatives in the list type.
