I agree with this, but the mechanism is already in place:
	set term pop
	set termoption enhance font "Times,11" ...

We would just need to expand the list of keywords accepted by
'set termoption'.    Hmm. "persist" might be a problem.

What do you mean "available"?
The value of GNUTERM is stored as the terminal name on entry.
So if you immediately do a "set term push", then you have
saved whatever the GNUTERM default was and can recover it
later with "set term pop".   

But yes, we could also copy it into a udv called GNUTERM.
That is so easy that I might as well just go ahead and add it :-)
