The fixup hook is in there, but it's not doing its job. I did note
that hitting M-g on the group before entering it fixes the
count. Perhaps this hook is not getting run upon initial connection.

Lovely. Is this something that I can appeal to my ISP's administrators
to enable, or is it an inherent feature lack in a given IMAP
implementation (in this case, Courier)?

Just to reiterate, though, .newsrc.eld is in fact quite necessary for
maintaining proper IMAP state if the server isn't as complicit as Gnus
would prefer. Perhaps we can move these nnimap marks out of
.newsrc.eld, or at least echo them into marks files like the NNTP
backends do.
