I feel like that's gotten pretty far away from the idea of a simple,
easy-to-use way of adjusting the parameters for one \g operation.
There'd be a whole lot of typing involved above and beyond the
obviously-necessary part of specifying the new pset parameter values.
(Also, it's not clear to me how that's any more robust than the
stack idea. If you could lose "\pset pop" to an error, you could
lose "\pset reset" too.)
If people are upset about the extra whitespace in the paren-style
proposal, we could do without it. The only real problem would be
if there's ever a pset parameter for which a trailing right paren
could be a sensible part of the value. Maybe that's not ever
going to be an issue; or maybe we could provide a quoting mechanism
for weird pset values.
