Re: git branch doesn't allow me to forcibly delete branch which was checked out in a now-deleted worktree dir

I know that I can just get rid of this error by pruning the worktrees,
but this still seems like incorrect behavior on the part of git branch.
It shouldn't be telling me that the branch is checked out in a directory
that does not exist, that is just factually incorrect.

Until the worktree status is updated git branch probably isn't
checking itself. It might be worth triggering a worktree prune when
doing branch work. Note that some worktrees may be on removable media
or similar, and thus even if the directory doesn't exist right now,
that does not mean it's no longer checked out. There is already
support for setting a worktree as "persistent", but this means git
branch definitely shouldn't just do its own check for non existent
directory.

Thanks,
Jake
