A patch for printing "match" when constructors are defined with let-in
but the internal representation dropped let-in.
Ideally, the internal representation of the "match" should use
contexts for the predicate and the branches. This would however be a
rather significant change. In the meantime, just a hack.
To do, there is still an extra @ in the constructor name that does not
need to be there.
