Support for using type information to infer more precise evar sources.
This allows a better control on the name to give to an evar and, in
particular, to address the issue about naming produced by "epose
proof" in one of the comment of Zimmi48 at PR #248 (see file names.v).
Incidentally updating output of Show output test (evar numbers shifted).
