Ick, no.  The original code is fine here, this makes it much harder to
understand what is going on here, right?

Same for this, and all the other changes you made.  The 80 column "rule"
is just a strong hint.  There are other ways to remove it instead of
just moving code to the left like you did here, if you really want to
fix these warnings up.
