This will break even more stuff than the last patch, ie, every single
stored rule or view that contains a TRIM function. You can *not*
eliminate, or mess with, the expr_list production, because that's what
dumping of these function calls relies on.
It's easily a dozen years too late to change this, Bruce. Please just
think about documenting the underlying functions, if you feel a need
to do anything here.
