Fix (I think) svnmucc's 'propset' command.
Fix (I think) svnmucc's 'propset' command.

* tools/client-side/svnmucc/svnmucc.c
  (drive): An OP_PROPSET should *open* the file or directory, not
    *add* it.  Correct that logic.
  (build): Fix the existence check to only apply when we know we
    aren't trying to add the propset target ourselves.
