emacs sources awash in trailing blanks

Gentlemen, emacs sources are the home of many stowaway trailing
blanks, hiding at the ends of lines, just waiting for their
opportunity to reproduce more of themselves thru a cut and paste by an
oblivious non show-trailing-whitespace using developer.
cd /usr/share/emacs/21.3/lisp/
LC_ALL=C grep -c ' $' *.el /dev/null

Customs, in a quick spot check of that emacs source directory, found
LC_ALL=C grep -c ' $' *.el |grep -v :0|wc -l
trailing blanks infected files.

"Stallman would spin in his grave if he went thru life with
show-trailing-whitespace enabled to see what was going on, and of
course if he were dead."

(The LC_ALL=C is needed to avoid the grep 3rd world locales slowdown bug.)

(show-trailing-whitespace is great for quibblers like me. "If you
can't attack their content, well, there's surely a trailing blank or two...")
