The variable GNUTERM is set to the starting terminal type on entry.
So you can execute "set term GNUTERM" when you want to go back to it.

I agree.  IMHO "set term push/pop" is misleading because you would expect
it to maintain a stack but it doesn't.

For that matter, "set term" is also a strange way to get a list of options.
"help term" or "help set term" would be more natural.

Anyhow, I think in the current versions "set term GNUTERM" is the best way
to get back to the starting state.  Perhaps "unset term" should do the same
thing, but that would be a change from previous versions.
