I assume it's probably something like mapping the FSF account "jimb" 
consistently to the most recent email id he's using in the logs as of the 
(re-)conversion date, since the CVS logs don't have the email info.  There are 
ChangeLog files which have email addresses, but since they're not a standard 
part of every software project, and they're not always updated as part of the 
same CVS commit (and certainly weren't updated in the same instant with RCS), 
it wouldn't surprise me if the conversion tool didn't try to use them for 
figuring out email addresses.  And really, it would be much more of a manual 
process, since the email address and FSF account name don't necessarily have 
some obvious and easy-to-program correspondence.

Even if someone did go back and rewrite the old commits with the old email 
addresses people were using at the time, I don't know about bzr, but git would 
see it as a completely rewritten history, resulting in new commit ids, etc.  
I've wasted enough time dealing with VCS issues with Emacs, and still haven't 
quite untangled from the bzr switch; personally I'd rather this just not get 
"fixed".
