Subject: imenu--generic-function broken for imenu-syntax-alist
Date: Tue, 20 Aug 2002 21:06:01 +0100	[thread overview]
Message-ID: <yebd6sdthw6.fsf@xpc21.ast.cam.ac.uk> (raw)


imenu is currently (in the trunk) broken for modes that define a value of
imenu-syntax-alist. For example, Fortran mode, Scheme mode.

The problem seems to be caused by this change:

	* imenu.el 
        [...]
	(imenu--generic-function): Use dolist.

        ;; The character(s) to modify may be a single char or a string.

      (goto-char (point-max))
      (imenu-progress-message prev-pos 0 t)
      (unwind-protect			; for syntax table



(dolist (c (car syn)) breaks because (car syn) is a string, not a list.

Any objections to reverting to mapc for this bit?
