[issue2651] Strings passed to KeyError do not round trip

Unassigning because others seem to be ahead of me reviewing this patch.   I will keep an eye on this, though.

Please note that I marked issue #614557 to depend on this one.  Adding 'key' attribute to exceptions is the subject of that issue.

While I support these features, I would really like to see a more comprehensive redesign as a part of PEP 3151.  I think it would be a mistake to rush something in before PEP 3151 is implemented and then discover that it was not the best choice as a part of bigger picture.
