Fantastic use of this information today: I had a problem with 0.7.x code,
so I grepped my commit mailing list archive for the function call (I
could also have used SVN Blame) and found a commit for it which included
the bug number in the commit message.
I was able to go straight to the bug and report the new problem. And the
code has been fixed already!
