error message when attempting to use ssh:// urlspec doesn't mention sftp://

I get:

% bzr push ssh://cs.widener.edu:devel/dosemu/
bzr: ERROR: Unsupported protocol for url "ssh://cs.widener.edu:devel/dosemu/": bzr supports bzr+ssh to operate over ssh, use "bzr+ssh://cs.widener.edu:devel/dosemu/".

Furthermore, when bzr+ssh fails (presumably because bzr is not installed globally on the target):

% bzr push bzr+ssh://cs.widener.edu/devel/dosemu/
Host key fingerprint is 98:e0:3e:03:90:88:90:71:7e:69:9b:c4:99:ab:62:93

bash: bzr: command not found
bzr: ERROR: Connection closed: please check connectivity and permissions

It seems like both of those would be a good time to point the user at "sftp://" and/or "bzr help urlspec"
