I thought we were supposed to _avoid_ mixing whitespace changes and
functional changes?

(Obviously the solution is to just only ever commit code with perfect
style to begin with so this is never an issue!  Speaking of which,
(setq show-trailing-whitespace t) is helpful to avoid this kind of
mistake up front.  git diff or git add -p will also flag this kind of
mistake, if you're working in git.  /usr/share/misc/NetBSD.el is also
helpful for other KNF style.)
