Yeah, I'm leaning to the idea that removing postfix operators from
b_expr is the least bad solution.

One thing that would have to be looked at is the rules in ruleutils.c
for suppressing "unnecessary" parentheses when reverse-listing
parsetrees.  It might be safest to just never suppress them around a
postfix operator.
