[PATCH 0/6] nd/worktree-move update

[Nguyễn Thái Ngọc Duy]

This

 - squashes in Johannes' fix (that's already on jch/nd/worktree-move)
 - fixes the compile problem on latest master (because prefix_filename
   takes one argument less)
 - fixes the test failure because real_path() is called twice (the
   first one hidden in read_gitfile_gently) but the output is not
   duplicated.
