Altered patch for nnimap.

[Lloyd Zusman <ljz@asfast.com>]

On and off over the past few months I've been having problems using
`nnimap': the message count wasn't getting updated in my `nnimap'
groups when I'd type `g' in the Groups buffer (i.e.,
`gnus-group-get-new-news').  I originally thought that this was solely
a function of the fact that I was using the University of Washington
imap software on my machine, but recently I converted to Courier imap,
with the same incorrect behavior.

A few weeks ago, Simon Josefsson sent me a suggested patch which was
hoped to be a fix for this problem.  Unfortunately, that patch didn't
work, but when I altered the patch to apply his changes to a different
function within `nnimap.el' than they were orginally applied to, then
things began to work correctly for me ... and with both the UoW and
Courier imap software, I'd like to add.

I then sent Mr. Josefsson my altered patch and this discussion in two
private emails about a week apart, but for some reason, either my
emails to him or his replies never made it.  Therefore, I'm posting
the altered patch here (below).

Comments?
