Right, I think in general you'll be better off to err on the side of
having Emacs symbols be "too short" (and hence having to grow them by
combining Emacs symbols with surrounding chars or surrounding Emacs
symbols) rather than having Emacs symbols be "too long" (and hence
having to parse the inside of symbols rather than treat them as "atomic"
