bug#35383: 27.0.50; Complete process of decoding Gnus group names

[Katsumi Yamaoka]

Ouch!  `gnus-newsrc-alist' in the .newsrc.eld file turned into a
list of just group names, i.e.:

(setq gnus-newsrc-alist '("nnml:foo" "nnml:bar" "nnml:baz"...))

Ok, I have a backup.  Not investigated it yet sorry, but I guess
this is due to the recent changes in the scratch/gnus-decoded
branch.
