I though we where moving away from special cases?  Anyway, empty selection do 
matter.  Consider this case:

I select a lot of code in another application.
I go to Emacs and set mark, then paste the code with mouse-2 and then M-x 
indent-region.

With your scheme, mouse-2 would fail to paste, which would be a nasty surprise.
