diff: properly error out when combining multiple pickaxe options
In f506b8e8b5 (git log/diff: add -G<regexp> that greps in the patch text, 2010-08-23) we were hesitant to check if the user requests both -S and -G at the same time. Now that the pickaxe family also offers --find-object, which looks slightly more different than the former two, let's add a check that those are not used at the same time.
