When we compare two directive, we are not cleaning up directive parameters of all spaces differences, which lead to merge divergence when the change is for ex a different line break caracter.

Most of the time, we won't care at all, and so we should let the user accept such change requests.

Actually, we should clean-up these one automaticatlly, and still let user accept change request on divergence (he knows better than us what he is doing).
