Andrew, any chance you could follow up on this?

I think it is genuinely necessary to do this, but I also think it needs 
to be
done at a higher level.

Namely, at WT.commit() and WT/Branch.push
That is what happened with set_rh(). We just stopped calling
'set_revision_history' when we switched to set_last_revision_info.

And theoretically, we only *need* to call 'set_last_revision()', so a 
future
branch format might only use that.

*I* am the one that broke set_rh, but that is partially because I didn't
realize I was breaking it, and partially because it needed to be 
switched. But
if we had a 'bzr commit fires set_last_revision hook', we would have at 
least
been aware and the opportunity to make a decision.
