I think there's an off-by-one in SOURCE-LOCATION. In Emacs, a buffer
starts at 1, but in Common Lisp a file-position starts at 0.
(Caveat: `(goto-char 0)' in DWIM fashion will also bring you to the
beginning of a buffer.)
I think that's the reason why you put the (PLUSP POS) there to guard
against this issue, but merely passing (IF POS (1+ POS) 1) should also
suffice. Perhaps you want to put this into an extra function so the
casual hacker will be aware of it more easily.
