dir.c::test_one_path(): work around directory_exists_in_index_icase() breakage
directory_exists_in_index() takes pathname and its length, but its helper function directory_exists_in_index_icase() reads one byte beyond the end of the pathname and expects there to be a '/'. This needs to be fixed, as that one-byte-beyond-the-end location may not even be readable, possibly by not registering directories to name hashes with trailing slashes. In the meantime, update the new caller added recently to treat_one_path() to make sure that the path buffer it gives the function is one byte longer than the path it is asking the function about by appending a slash to it.
