So it seems we're different.

Actually it's #2, and to quote a different review[1]:

	Reviewers hint to a correct solution and you are supposed to
	lookup what that solution means and act accordingly. If you do

actually it's not a script, but I guess that doesn't matter much.

It might save the patch sender from a third iteration.

The functionallity of the patch has been questioned before so I didn't
see a value in repeating that :-)  To be honest, I didn't check for
functional problems, but IMHO it's OK to provide feedback about a part
of the problems if you don't see all of them.
