Re: [PATCH v4 6/8] worktree: add relative cli/config options to `move` command

[Phillip Wood <phillip.wood123@gmail.com>]

Hi Caleb

This looks good, I've left a couple of comments on the tests - they 
could be cleaned up like the last patch. The implementation looks good.

By the time this function is called we've already initialized 
use_relative_paths from the config setting - good

As with the last patch we should use test_config and stop copying files 
just to compare them. It's probably worth checking the gitdir file as 
well as .git here as well.

We used to append "/gitdir" below but now we do it all in one - nice.

get_linked_worktree guarentees that wt->path is absolute so this looks good.

This is a nice simplification
