We get to vc-do-command like this:
 vc-bzr-state -> vc-bzr-status -> vc-bzr-command -> vc-do-command

vc-bzr-command is passed a 0 for OKSTATUS.
but 
bzr status revdiff 
returns 3, that is why the message above is printed.
Changing that 0 to 3 helps, but then vc-bzr-state prints 
"bzr: ERROR: Path(s) do not exist: revdiff".

Maybe we can make vc-bzr-status ignore that message.

I'd like to get a second opinion before making the 2 changes above (0->3
and ignore the error message).

The calls above occur after the checkin has been completed.
