The statement was correct as given so I didn't remove it. (If you think
it should mention that SIGHUP works, there are several dozen other uses
of the identical wording to describe SIGHUP variables ...)

I moved these down a little, since it didn't seem to make sense to
provide an example before all the relevant variables had been discussed.

I'm not sure about the markup here; it might be better to break out of
the <variablelist> and format the examples as independent paragraphs.
Comments anyone?
