I was under the impression that 'set term push/pop' was a stack,
but I see that I was wrong.
The truth is that I have never used this mechanism.

OK. But then the name "GNUTERM" is slightly misleading.
Should it rather be "DEFAULT_TERMINAL" or something like that?

By the way, saving the value of GNUTERM internally allows this
rather neat trick, where the terminal options are kept also:

[1] setenv GNUTERM "post eps solid color lw 2"
[2] gnuplot
...
gnuplot>   set term <something_else>
gnuplot>   [... do a bunch of stuff ...]
gnuplot>   set macros
gnuplot>   set term @GNUTERM
gnuplot>   show term
Terminal type set to 'postscript'
Options are 'eps noenhanced defaultplex \
   leveldefault color colortext \
   solid dashlength 1.0 linewidth 2.0 butt \
   palfuncparam 2000,0.003 \
   "Helvetica" 14 '
