Well, it's a sub-list of the entire output of helpVariables(), so
I think some indentation is a good idea.

But we could do something close to that, say two-space indent for the
variable names and four-space for the descriptions.

Yeah, we're already past the point where it's likely that
helpVariables()'s output would fit on one screen for anybody, so
maybe this is the best way.
