Right, that's a bug; the code is assuming too much of the input. Thanks for

Yes, a patch would certainly be welcome if you like to work on it.

My suggestion is that get_relative_path essentially should stay the same and
continue to assume that the paths are well-formed and canonical.
make_relative_path (the only caller of get_relative_path) should canonicalize
current_working_dir and path by calling realpath(3). Does this sound reasonble?
