Ping indeed?
Yeah, right, sorry. Non-subscribed occasional gmane-reader here amidst
job hunting, so thanks for the ping. And the re-ping...

This is RFC since this is my first foray into the Git completion script,
and there are likely better and more idiomatic ways to accomplish this.
Using __git_find_on_cmdline() to find subcommands and case
"$subcommand,$cur" to limit the number of nested case statements is as
idiomatic as you can get in the completion script.
And I hear you, that "<path> first, <refname> second" syntax makes it way
too complicated, especially since they can follow '-b <refname>'.
I wrote a completion function for 'git worktree' as well, turns out a week
or two before you posted this, but I never submitted it as it was way too
convoluted. Anyway, will send it in reply to this, just for reference.

A more descriptive variable name for 'n' would be great.

We usually don't offer '--force', because that option must be
handled with care.

I suppose here you wanted to calculate where (i.e. at which word on
the command line) we should offer refs and fall back to bash builtin
filename completion otherwise. It works well in the common cases,
but:
- it doesn't offer refs after -b or -B
- it gets fooled by options to the git command, e.g. 'git
--git-dir=.git worktree add <TAB>' offers refs instead of files,
'git --git-dir=.git worktree add ../some/path <TAB>' offers
refs, etc.
