I discovered what's wrong. The problem is caused by a bug of
XEmacs 21.4. Emacs 21.x and XEmacs 21.5 return `0' for the
following form, but XEmacs 21.4 returns nil for it.
(let ((subject "Re: [Exim] Exceptions to globs")
(regexp "^\\(?:R[Ee]: +\\)*\\(\\[Exim\\] *\\)"))
(string-match regexp subject))
The reason why the list identifier is removed in the parent
article is that the subject doesn't begin with `Re: '.
A special regexp called `shy group' is there. XEmacs 21.4
supports it but doesn't seem to work in some cases. The recent
Gnus uses it in several Lisp modules, however I don't know
whether we should restore all or some as before.
If anything, I don't feel like degenerating them. Because using
`shy group' is hopeful to improve the performance. Isn't there
a chance of fixing XEmacs 21.4?
