PATCH: Fix completion for Subversion 1.7

[Simon Olofsson <simon@xxxxxxxxxxx>]

Hi,

as previously mentioned on this list, the completion for Subversion 1.7 
is broken because `svn help' outputs
  --changelist [--cl] ARG
for some commands (e.g. `update').
Attached is a Patch that fixes this (Till Haselmann confirmed it). Or 
you can merge from here:

Regards,
Simon
