Can't retreat either

Can't retreat either

[Harry Putnam]

In an attempt to get away from irritating behavior in current cvs
gnus, (posted here under thread "Something very wrong", I backed off
to gnus_03 but find now I cannot open any groups.

Afer closing gnus and emacs, I reaimed gnus at the appropriate
directory of lisp files.  From gnus_04 to old gnus_03 installation.

Then removed all .marks and .overview files under ~/Mail.
Started gnus, who came up as the new (old) version, then ran 
M-x nnml-generate-nov-databases.

Only after that completed did I try to open a group.  Gnus won't let
me and throws an error that may be a clue about my earlier troubles
too.

Backtrace below, can someone see what the trouble is?
`gnus-correct-length' appears only in ~/.newsrc.eld.  Is not found in
any of the *.el files under my gnus_03 tree.  

In fact it appears in /usr/local/gnus_04/lisp/gnus-spec.el, from my
gnus current cvs directory.  So this is code added since gnus_03 and
might possibly be the source of my troubles.

How can I back up gracefully to a gnus that didn't use this code.  Can
I simply remove the section from .newsrc.eld that contains
gnus-correct-length?

(setq gnus-format-specs nil) fixes the problem.

No `gnus-compile' here:

grep 'gnus-compile' .gnus <RET>
<nothing>

Hasn't been recreated either.  

What does that chunk of code do anyway?

Excised from .newsrc.eld (wrapped for mail):

(setq gnus-format-specs '((version . "21.0.104.1") (summary-dummy "
%(: :%) %S\n" (progn (insert " ") (gnus-put-text-property (point)
(progn (insert ": :") (point)) gnus-mouse-face-prop gnus-mouse-face)
(insert " " gnus-tmp-subject "\n"))) (summary-mode "Gnus: %g [%A] %Z"
(concat (format "Gnus: %s [%d] %s" (gnus-short-group-name
gnus-tmp-group-name) gnus-tmp-article-number
gnus-tmp-unread-and-unselected))) (summary "%2t%U%R%7d%z%I%(%[%4L:
%-20,20f%]%) %s\n" (progn (insert (format "%2d%c%c%7s%c%s"
(gnus-summary-number-of-articles-in-thread (and (boundp 'thread) (car
thread)) gnus-tmp-level) gnus-tmp-unread gnus-tmp-replied (gnus-dd-mmm
(mail-header-date gnus-tmp-header)) gnus-tmp-score-char
gnus-tmp-indentation)) (gnus-put-text-property (point) (progn (insert
(format "%c%4s: %-20s%c" gnus-tmp-opening-bracket gnus-tmp-lines (let
((val (eval (gnus-summary-from-or-to-or-newsgroups gnus-tmp-header))))
(if (> (gnus-correct-length val) 20) (gnus-correct-substring val 0 20)
val)) gnus-tmp-closing-bracket)) (point)) gnus-mouse-face-prop
gnus-mouse-face) (insert " " gnus-tmp-subject-or-nil "\n")))))

That's right, you can just remove the (setq gnus-format-spec ...)
statement.  I think this comes from (gnus-compile) in your .gnus file,
so it will be recreated the next time Gnus starts.
