Complete paths after 'git worktree add <TAB>' and refs after 'git
worktree add -b <TAB>' and 'git worktree add some/dir <TAB>'.
Uncharacteristically for a Git command, 'git worktree add' takes a
mandatory path parameter before a commit-ish as its optional last
parameter. In addition, it has both standalone --options and options
with a mandatory unstuck parameter ('-b <new-branch>'). Consequently,
trying to complete refs for that last optional commit-ish parameter
resulted in a more convoluted than usual completion function, but
hopefully all the included comments will make it not too hard to
digest.
