Comment (by mojca@…):

 I went ahead and committed r120972 (mostly Bradley's patches, slightly
 modified).

 Replying to [comment:15 pixilla@…]:
 > I use a script to generate patch files that conform to MP standards of
 patch-path.diff.

 So just a provocation then: what's your excuse for using (long) path
 prefixes?
