I'd even prefer

     $ bzr-dev.my# bzr ci -m "bzrlib/builtins.py:status help listing"
     modified bzrlib/builtins.py
     commited revno 1193
     $ <cursor here>

Since the commit is supposed to be atomic, the message "commited ..."
right after the end of the transaction is a confirmation that everything
is went fine.
