I think that would be good too.  For example, people uploading files
to a web server might like to say

  rsync -avzP --chmod a+rX ./ sourcefrog.net:/home/www/sourcefrog/

Ideally the patch would implement as many of the gnu chmod semantics
as possible.  I think the mode parser should be a separate function
that passes back something like (mask,set) description to the rest of
the program.  For bonus points there would be a test case for the
parser.
