Linus and whitespace

Gentlemen, I couldn't help but notice a certain Linus B. Torvalds is producing mail with trailing whitespace.

I recall one should (linux-doc-*/Documentation/CodingStyle*:) "Get a decent editor and don't leave whitespace at the end of lines."

Indeed, with my GNU Emacs show-trailing-whitespace X-ray eyespecs on all day, whitespace becomes screaming purple space, so you can't blame me for noticing.

Anyway, I have analyzed his messages, (User-Agent: Alpine 2.00 (LFD 1167 2008-08-23)) and discovered that the whitespace phenomenon almost always occurs if the lines are more than 60 characters long, the "danger zone", we might say.
