I don't think it'll be much bigger.  And it has the benefit of being
cleaner.  Otherwise you get problem that when SWI-Prolog is run from
a Makefile that sets EMACS to "emacs" (or somesuch) it'll think it's running
inside Emacs.
So since we're going to break the "test if $EMACS == t", it's a good
opportunity to fix it right, rather than fix it by half only.
