    In zwei in System 78.34, ZMail 38.5, microcode 836, " VAX", on Lisp Machine Twenty:

    I was reading in ai:lmdoc;bug lispm into the editor and after
    56% of it was read in I got the following error:

    >> error: The argument function-spec was NIL, while in
    SI:function-spec-get <- Zwei:sectionize-buffer <-
    Zwei:sectionize-buffer

    It happened a couple of times.

I have always been skeptical of the wisdom of having the editor come up
in lisp mode by default in files which don't have either a "LISP" type
or a -*-Mode: Lisp-*-.  These problems will always arise as long as
this is the case.
