Oh, right. That's OK too.

It's not important, but I disagree a bit with that characterization. This is not
just for backward compatibility. If you provide size in the input pattern, then
it should be taken into account, regardless of the Emacs version (going backward
or forward). Same thing with other input fields - they need to be matched and
retained.

I mention this because that comment might lead someone to believe at some point
that this was no longer needed.

Thx.
