rsync - Apr 2014 - rsync-3.1.0 bug in cmdline parsing for option --usermap and --groupmap

Hello!

I think there is a small bug in cmdline parsing for option usermap and
groupmap. If you give multiple mappings to --usermap or --groupmap, only
the first one is used.

Example: rsync -a --usermap=userA:userB,userC:userD <src> <dst>
-> Only the user mapping for userA to userB is used, the second mapping is 
ignored.

The attached patch fixed the problem for me.

Greetings Dieter

I haven't seen that issue.  Your patch fixes an issue with
--usermap=MIN-MAX:NEW not parsing, and I have incorporated that into the
git repo -- much appreciated!  If there is any other bug remaining, let me
know.
