[PATCH] updated patch to --help -r

* subversion/clients/cmdline/main.c
  (svn_cl__options): Rephrase help for the '-r' option to include
  short descriptions of the BASE, HEAD, COMMITED and PREV revision
  keywords. Help for this option now extends over several lines.

Thanks for the correction, Philip. Is this better?
