Stampity stamp LGTM

though I see plenty of opportunities to undo line wrapping where there were no
opportunities before.

I think I re-wrapped/unwrapped all the lines where it makes sense to do so
(i.e., where it'd be consistent with the rest of the file's style). There are a
couple files with lots of near-misses though, where it looks like you can
unwrap, but you miss by a character or two (nooooooooooooooooooooooooooooo).
