The entire tree's polluted with inappropriate trailing whitespace. This commit rids our environment of all of those useless keystrokes. Unfortunately, it sure ain't a permanent solution and requires every contributor to instruct their editor(s) to prevent or eliminate them. Plus it's strongly recommended we all insert something like what's shown below to our '.gitconfig' file so as to provide at least some warnings when we try to apply any patches (git am) that do contain the #@!%& things!
