Here's a new patch that fixes the grammar ugliness (amazing how easily I
got that to work after a week of not looking at it!) and adds an
(Expr *) link in FmgrInfo. It passes all regression tests. If there are
no objections, please apply.

(as phase 1 -- see:

for what the patch covers and the planned "yet-to-come").

Thanks,
