I will look at the rest of this, but in the case of GNU emacs, for
instance, the above is not true.  Emacs either keeps isig and makes
^G the interrupt character, or sets -isig and sends SIGINT to its own
pgrp when it reads ^G.  Regardless, an enclosing script gets a SIGINT
when you use ^G in GNU emacs.
