 With two directories, it prints either the files common to both DIR1
 and DIR2 or, with the `not:' prefix, the ones present in DIR1 and not
 in DIR2. The `and:' prefix is assumed by default and necessary only if
-you have a directory name starting with `not:'.
+you have a directory name starting with `not:'. Files are handled like
