Right. Hitting `e' in *Article* buffer causes this problem. Besides,
it will not decode MIME either.

Different functions are called for hitting `e' in *Article* buffer and
*Summary* buffer. Therefore, I am wondering whether we should remove
function `gnus-article-edit' and use `gnus-summary-edit-article'
instead.

As a hot-fix, evaluating the following lines may help.

(gnus-define-keys gnus-article-mode-map 
        "e" gnus-article-read-summary-keys)

I am not sure what caused Ted's bug. Maybe the separating blank line.

To bring back those missing articles, I tried to move all articles in
the group to a temporary group, then rescan the group, and repeat
until no articles show in the group.  It was long time ago. I also am
not sure whether it works for Ted's situation.
