   file_search(foobar) returns the path of foobar, which must be something
   in file_search_maxima. I guess you could then parse the path to get just
   the directory. There might be some Common Lisp functons to help with
   that but I don't know for sure.

pathname_directory in src/mload.lisp will extract the directory bit for you.
Try

? pathname_directory
