It's just an application of reasoning: is "a single-line is not
sufficient", that must mean that there's more than one line involved.
I added the "presumably" because some user somewhere might decide he
likes to use this hook for something else.

I'm in a bad position to fix it, because AFAICT the text already says
very clearly what the var does, and when it makes sense to use it.
Could you provide a sample patch that would make the text clear to you?
