Hmmm, not so sure if I got everything right leading up to
this point.
But GEM itself does not actually interact in any way
with gis.m.
Rather, it works like this (or read the docs that come with GEM):

1. an extension package _may_ contain menu entries for gis.m.
This is a plain ASCII file containing tcl code.
That ASCII file gets copied into $GISBASE/etc/gm/Xtns/

2. gmmenu.tcl sources that tcl snippet into the menu list.

Thus, in whatever way gis.m will handle xterm etc., it's
just a matter of updating one ASCII file in the extension package
to produce the right code.

I think ...
