Thanks, but I still don't think I understand (or if I do, cannot
reproduce).  The command bound to 'M' is documented thus:

  Mark all files with the same state as the current one.
  With prefix argument ARG, mark all files (not directories).
  If the current entry is a directory, mark all child files.

So if point is on a directory, the files under that directory should
be marked.  In your case, if point is on the line which says "lisp/",
the file lisp/init-org.el should be marked.  Does that not happen?

Or what doesn't happen in the example you show (please also tell where
point is when you press 'M')?
