Bikeshedding: I wonder if this would be more intuitive if called
simply "/HEAD" rather than "main/HEAD".

If the input is "worktrees/refs/" (nothing following the trailing
'/'), then an empty string will be passed to is_pseudoref_syntax(),
which will return true. Does that result in correct behavior? (Same
question about "main/" being passed to is_main_pseudoref_syntax().)
