Actually, no, "^\n" is not a multi-line pattern (yes, it's right there
on the border, but it's on the right side of the fence).  And "^\n+"
should work as well (as long as we the behavior is the same as with
"^\n", tho slightly optimized), even though it *is*
a multi-line pattern.

Oh, I'm not so concerned about the *Help* buffers, it's the source code
that annoys me (that's where I work and where I don't want to waste
screen real-estate).
