Normally an edit requires

• three people to approve, or

• two to reject, or

• the original poster or a single moderator to make a decision

The edit had one approval vote at the time of writing. In lieu of waiting for at least two further users to check the review queue, I have approved the edit.

I think it would have been better posted separately, so I earlier chose not to approve or reject, but give the community a chance to decide either way (since the original answer was right in result but totally wrong in reasoning).
