It doesn't have to work on Emacs-24. I don't use Emacs-24 to develop in,
only Emacs-25, at least partly because Emacs-25 doesn't (didn't) set
EMACS=t.

At this juncture, I think the sensible thing is to give up on using
EMACS as both an environment variable and a makefile variable. Putting
hacks into my make file to distinguish between running inside and
outside of Emacs is not a solution. The same make file should work.

To repeat, my belief is that a behaviour that was installed
deliberately, and which has been on master/emacs-25 for a year should
not have been removed in pre-test. I think Stefan's patch needs
restoring. Are you prepared to do this?

Failing that, I will back out my changes to cask.
