 Notes:
   Using "-f directory" may give unexpected results:
-
-  Used with "--git", git signators for _all_ files in and below
-     directory are examined as git recurses directories.
-     Any specified X: (exclude) pattern matches are _not_ ignored.
-  Used with "--nogit", directory is used as a pattern match,
-     no individual file within the directory or subdirectory
-     is matched.
