The whole error reporting scheme needs some loving care, and I've got a
partial patch series posted to the list earlier that started that
process.  But it was deemed less important than getting 0.8.2 finalized
(as well as helping with RHEL-6 backports), so it's been on the back
burner.  At this point, a minimally-invasive patch, like Daniel's
proposal, is better than making things better when the code is all going
to be refactored down the road anyways.  But thanks for the thought; it
may affect my refactoring efforts!
