That's still not quite clear. What will happen in each of these cases:

* No SSH library available, access ‘bzr+ssh’ URL
* OpenSSH only available, access ‘bzr+ssh’ URL
* Paramiko only available, access ‘bzr+ssh’ URL
* OpenSSH and Paramiko available, access ‘bzr+ssh’ URL

Or, better, could it be phrased as a “When accessing ‘bzr+ssh’ URLs,
Bazaar will use the first available of LibFoo, then LibBar, then LibBaz,
and finally raise an OhNoesError if none of those libraries are
available”.
