But that's not something which happens very often, is it?

IOW, this looks like a relatively unimportant asthetic issue that
doesn't justify strong opinions in either direction.  Even though
there's no guarantee that the printed representation of symbols will
remain stable, we might as well do Tom the courtesy of reverting that
particular change, since it caused him problems with code problem-free
since Emacs 18.
