The behavior of the svn cp command is consistent with the behavior of
the Unix cp command.

If you're talking about parsing for the message "svn: URL 'http://
whatever/branches/whatever' non-existent in that revision" then I
would advise against that. Sure, it could change.

"svn ls <nonexistent_url>" does return an exit status of 1, so I
would recommend using that instead. I'm using Subversion 1.4.4; if
you're using an earlier version, you should probably upgrade. This
may have been fixed recently.
