worktree: add skeleton "repair" command
Worktree administrative files can become corrupted or outdated due to external factors. Although, it is often possible to recover from such situations by hand-tweaking these files, doing so requires intimate knowledge of worktree internals. While information necessary to make such repairs manually can be obtained from git-worktree.txt and gitrepository-layout.txt, we can assist users more directly by teaching git-worktree how to repair its administrative files itself (at least to some extent). Therefore, add a "git worktree repair" command which attempts to correct common problems which may arise due to factors beyond Git's control. At this stage, the "repair" command is a mere skeleton; subsequent commits will flesh out the functionality.
