The current situation is definitely a problem.  If I am in a worktree,
using "head" should be the same as "HEAD".

I am not sure if you mean that the fix is too narrow or too wide.
Maybe it is only necessary in 'is_per_worktree_ref'.  On the other
side of the coin, I could change every strcmp to strcasecmp where the
comparison is against "HEAD".
