Fixed.  I must apologize to XEmacs users who keep track of the
latest Gnus.  If you have the nnml groups of which the names
contain non-ASCII characters, you want to fix the ~/Mail/active
file, and possibly the ~/.newsrc.eld file, manually.  Beat me!

The purpose of the change I did last was to make sure the names
of groups, that nnmail-split creates[1], in nnml-group-alist are
encoded.  However, it encoded not only newly created group names
but also existing ones.  It happens only in XEmacs.  In Emacs,
the double encoding is not happen even if using encode-coding-string
twice.

(decode-coding-string
 (encode-coding-string
  (encode-coding-string "hyskenstræde" 'utf-8)
  'utf-8)
 'utf-8)
 => "hyskenstræde"

This is why I didn't notice the ill effect of the last change.

[1] The case where the regexps in the splitting rules have
 something like "\\1" that is replaced with the actual text.
