The option parsing code in svn is common to all the subcommands, thus
all the subcommands accept -rX:Y at option parsing time, even though
some of them can only handle the -rX form. The subcommands that only
handle the -rX form should produce an error if invoked with -rX:Y,
unfortunately not all of them do, some silently ignore the :Y part.
