Fixing #1225: we now skip the canonically built binding contexts of

the return clause and of the branches in a "match", computing them
automatically when using the "at" clause of pattern, destruct, ...

In principle, this is a source of incompatibilities in the numbering,
since the internal binders of a "match" are now skipped. We shall deal
with that later on.
