[PATCH 0/6] completion: improve completion for 'git worktree'

Complete paths of working trees and refs for 'git worktree's various subcommands.

The last two patches do the actual improvements, the first four are preparatory steps.

An early version of the last patch was already sent to the list as a PoC over four years ago [1], but I didn't like the part completing options for 'git worktree add', and thus never seriously submitted it. I still don't really like that part :), but it is really useful when working with working trees, and at least other parts of the completion function got simpler (thanks to automagically completing --options via parse-options, and after the preparatory steps in this series).
