Thanks.

I can agree that patch 1 is simpler and might be preferable, but given
the pre-existence of `x', I'd rather preserve its behavior.
Furthermore, I do use `x' fairly often and usually without paying much
attention to where I am.

So, I installed patch 2.

Indeed, from the submitter's point of view, they're indistinguishable.
Usually, if I'm the reviewer and the review isn't coming back quickly
... well let's just say it's not because I'm a perfectionist.
