I really have nothing more to say on this.
I would just be repeating myself. In any case,
we've agreed that it's unlikely that the bug
will be fixed. And although I thought at one
time that you agreed the bug existed, I'm not
so sure now that you did. And as, IIUC,
Andreas points out, clisp apparently just
substitutes a different char for "," internally
when it handles backquote, which just punts the
problem to a different corner case (different
char). So I guess nothing will be done, and
maybe nothing reasonable can be done, for this.
