There are other values:  'x', 'j', and '=' followed by the name of a newsgroup (alias).

I believe the best would be to use what INN mentions in its documentation!  (Or otherwise, RFC 3977 and RFC 6048.)

It would then give:

-------------------------------------------------------------------------------------
... and *flag* usually takes one of these values:

    y         Local postings and articles from peers are allowed.
    m         The group is moderated and all postings must be approved.
    n         No local postings are allowed, only articles from peers.
    j         Articles from peers are filed in the junk group instead.
    x         No local postings, and articles from peers are ignored.
    =foo.bar  Articles are filed in the group foo.bar instead.

If *flag* has another value, then the status of the newsgroup should be considered
to be unknown.

Can a bullet list be used in the documentation, to properly indent the flag values?

Improvement committed in r86140, thank you!
