A small procedural request

Hi,  I have a very small request to those committing into head.

If you commit a fix, then if it is possible to easily do so, can you 
give the revision number in which the regression was introduced?

like "this was  broken in r329xxx"

this allows people who are looking for specific problems to say "Ok 
that bug was introduced after the snapshot I'm working on and can't be 
my issue".

(we are not always working on the very tip).


thanks

Julian
