    Improve printing of Orig RdrNames · 30ced404
    simonpj@microsoft.com authored
    In Tempate Haskell -ddump-splices, the "after" expression is populated 
    with RdrNames, many of which are Orig things.  We used to print these
    fully-qualified, but that's a bit heavy.
    This patch refactors the code a bit so that the same print-unqualified
    mechanism we use for Names also works for RdrNames.  Lots of comments
    too, because it took me a while to figure out how it all worked again.
