I think I've figured it out now.  When Gnus finds that an article does
not exist, it marks it as read.  But nnmaildir doesn't store marks for
nonexistent articles.  (Does nnimap?  nnml?)
nnmaildir-request-update-info returns only the marks it knows about;
it removes marks supplied by Gnus that weren't stored by nnmaildir.
So after it's called, all the nonexistent articles seem to exist as
unread, as far as Gnus is concerned.  Even if nnmaildir is the only
backend currently affected by this problem, I think it makes sense to
fix this in Gnus:  gnus-request-update-info could artificially add
(1 . (1- min)) to the read range after getting marks from the backend.
Thoughts?  Objections?  Other ideas?
