I am using a brute force method of stopping myself from writing long

    (delete-char -1)
    (beep)))

(add-hook 'after-change-functions 'my-dont-insert-after-fill-column)

But I discovered this is also acting on the command buffer, so I
cannot add more than my fill column when doing simple file copies or
renames or text search & replaces.


Well, you could just check whether the current buffer is the
minibuffer:

(when (and (not (minibufferp))
           (> (current-column)
              fill-column))
  ...)
Hi Oliver,
emacs is choking on (minibufferp) - says it's a null-function. I presume it's saying it doesn't exist? I can't find any mention of it in the help.
