isl_transitive_closure.c: path_along_delta: try and avoid splitting off identity
Usually, path_along_delta returns a union of the identity mapping and
of paths of length at least 1. In some cases, the paths of length
0 correspond exactly to the identity mapping and then it is more
efficient to return a single mapping with paths of length at least 0.
