Motivation for this change
We use this lemma in the proof that monotonic functions have a countable number of discontinuities
which we plan to use in the development of absolute continuity
TODO: check whether the lemma inDONEclassical_sets.v
is not superseded by #1246 before merging@IshiguroYoshihiro
