The svn client program returns 1 to indicate an error happened, just
like most programs do. It would be really strange and inconsistent,
IMO, to have 'return 1' mean something completely different just
because you invoked the 'diff' subcommand.

If you want to know whether a diff occurred, couldn't you just check
to see if any lines were printed to stdout? :-)
