Before, we would only wrap in sets that extend beyond exactly

We now extend this process in several ways.
First, the wrapped-in set is allowed to extend beyond several facets.
Second, the wrapped-in set need not have facets adjacent to these facets.
It is sufficient that the adjacent facets are valid for the wrapped-in set.
Finally, the wrapped-in set is allowed to be of a lower dimension.

Commit 39345fc (isl_transitive_closure.c: path_along_delta: try and avoid

However, it would only check if relaxing the length to zero would
not introduce any extra elements. The path may have constraints
on the parameters, though, and so we may actually be removing elements.
This means that we need to check for equality with the identity relation.
Perhaps this makes the whole optimization pointless.
