I thought you were saying that EPUB should be treated the same as
HTML, PDF, DVI, etc., in which case the EPUB directory should default
to docdir, but, like htmldir and dvidir, allow installing EPUB in
another place.  That made sense to me, but then came your last
sentence and confused me, because it actually says EPUB will NOT have
its variable, unlike those other formats.  Such a difference should be
due to some valid reason, IMO, but you don't say what would such a
reason be.
