I think this operation is common enough to be runnable after upgrade
(but only if the upgrade was successful). If we separate them users
might end up removing backup.bzr in places where the upgrade was not
succesful and end up losing data.

As a side-note I think 'bzr clean' is a confusing name. The name
doesn't really indicate how it is different from 'bzr clean-tree' and
git has a 'git clean' command that behaves similarly to 'bzr clean-tree'.
I much prefer 'bzr garbage-collect' (did that have the same function?) that 
was proposed earlier. 

Cheers,

Jelmer
