I don't think 4 should match anything.  It could refer to many versions
and that's confusing, and we aren't having problems with people using 4
and expecting it to work.  So I would drop 4 change, and keep 5/6/7 and
then I am in favor of your patch.

I would like to deprecate and eventually remove 7.x and make only 7
legit (similary 5 and 6).  But the removal is less important, especially
if pkglint warns on the longer forms.
