--- Comment #22 from Jeffrey A. Law <law at redhat dot com> ---
Patch to match.pd fixes the regresssion on the trunk.  Will be opening a
separate BZ for the missed optimizations.

Given the fix depends on the match.pd functionality, I don't see any chance
we'll ever backport this to the release branches.
