Some third party Git tools provide a man page, which we can at least use
for completing options.
The old logic excluded all generated completions for Git subcommands.
Instead, try to load completions for all available external subcommands.
We can use $PATH/git-* because /bin/git-add and friends were removed in Git
1.6.0 in 2008.
Closes#4358 (the "git-foo" wrapping was added in #7652)
Since #7075, git-foo.fish files are sourced when Git completions are loaded.
However, at least Cobra (CLI framework for Go) provides completions like
complete git-foo ...
This means that completions are only offered when typing "git-foo <TAB>"
and not on "git foo <TAB>". Fix this by forwarding the completion requests.
Take care to only forward if there are actually completions for "git-foo",
to avoid adding filename completions.
It also reflows.
We might want to think about doing something more extensible here, as
konsole is also about to add reflow, but for now the main problem
children here are VTE and alacritty.
Extends #7491.
Prior to this change, a glob like `**/file.txt` would only match
`file.txt` in subdirectories; the `**` must match at least one directory.
This is historical behavior.
With this change we move a little closer to bash's implementation by
allowing a literal `**` segment to match in the current directory. That
is, `**/foo` will match both `foo` and `bar/foo`, while `b**/foo` will
only match `bar/foo`.
Fixes#7222.
Prior to this change, if fish were launched connected to a tty but not as
pgroup leader, it would attempt to become pgroup leader only if
--interactive is explicitly passed. But bash will unconditionally attempt
to become pgroup leader if launched interactively. This can result in
scenarios where fish is running interactively but in another pgroup. The
most obvious impact is that control-C will result in the pgroup leader
(not fish) exiting and make fish orphaned.
Switch to matching the bash behavior here - we will always try to become
pgroup leader if interactive.
Fixes#7060.
