That doesn't apply in your case. It's for packages like compiz that were
last seen in squeeze (or something) and reappeared in stretch (with
sightly different package layout), having upgrade problems if some old
bits were still installed.

Unlike many other packages, the old emacsXX packages seem to stay
(co-)installable forever ... there is nothing on the upgrade path that
makes them go away. But having them installed, triggers stuff to be run
with them at installation time of other packages.

I would probably add
  Breaks: emacs23
(and maybe more old versions previously covered by the removed checks)
for one stable release and thereafter you can be sure that these old
cruft versions can't do harm to your package in the future.
