BTW, I have no plans to merge that.

It seems that you are putting too much code in the vc-bzr, not in vc
itself.  Better pass the buffer to the command, instead of creating it
locally in each VC backend.

In the buffer?  The way pcl-cvs does it is a bad idea, I am completely against it.
Putting something in the modeline, like the rest of the vc
asynchronous commands do would be better.
