grep (was Re: inconsistent behavior of M-x info)

[Joe Corneli]

Well, to continue my non-grep-mode-havin' saga, in my cvs emacs of 
yesterday night, 

M-x grep

produces

Loading grep...
execute-extended-command: Symbol's value as variable is void: grep-mode

However, upon issuing emacs-lisp-byte-compile-and-load in grep.el, I
can grep.

The problem seems to have to do with the following:

;;;###autoload (autoload 'grep-mode "grep" nil t)
(define-compilation-mode grep-mode "Grep"
  "Sets `grep-last-buffer' and `compilation-window-height'."
  (setq grep-last-buffer (current-buffer))
  (set (make-local-variable 'compilation-error-face)
       grep-hit-face)
  (set (make-local-variable 'compilation-error-regexp-alist)
       grep-regexp-alist))

I think the autoload was accidentally commented out, and the above
should read

;;;###autoload 
(define-compilation-mode grep-mode "Grep"
  "Sets `grep-last-buffer' and `compilation-window-height'."
  (setq grep-last-buffer (current-buffer))
  (set (make-local-variable 'compilation-error-face)
       grep-hit-face)
  (set (make-local-variable 'compilation-error-regexp-alist)
       grep-regexp-alist))

(autoload 'grep-mode "grep" nil t)


In fact, I tested this out, and now a new emacs is aware of
grep-mode and *can* run grep.


Here are my emacs's details.
