Replying to [comment:1 vbraun]:
> I changed the "empty" polyhedron to contain one equation `0==-1`.
This seems reasonable, but it shows in the doctest as "[An equation () x +
-1 == 0]" which is confusing: what is "() x" and why "+ -"?
This is not directly related to this ticket, but how about omitting "() x
+" for 0-dimensional equations/inequalities and taking into account the "+
-" situation in general?
