As Diez mentioned, an option defaulting to off would be interesting to play
with.  I generally discourage using vertical whitespace inside methods, and
mostly use it for structural separation, so I think this might be reasonable.
It could only apply to actual blank lines, i.e. comments wouldn't trigger it.

Actually, that else gets lined up under 'if' right now.

So I guess you're saying the blank line would add an extra dedent level?  I
hate to have people start to rely on this behavior to add non-structural
vertical whitespace.  If this feature is more helpful for top-level
structures, then it might be useful, otherwise I'm skeptical.  But as I say,
it might be interesting to play with.
