completion: list paths and refs for 'git worktree add'
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.
