Sorry, I let this patch slip last time.  Thanks for resubmitting.

Unfortunately, this needs to be merged with the regular pasting code,
which itself needs some work.  Probably with regular paste querying
for formats we want and calling an underlying 'getdata' function.
Paste special would also call this function with the format specified.
Additionally, all of this should use the Ole clipboard rather than the
user32 api.

Also note, we don't want C++ style comments in Wine.

Huw.
