I save the time stamp but it's not used.  The way CouchDB works is the
revision gets incremented (it looks like "23-md5hashhere") on save and
you get it back.  You have to provide the latest revision to overwrite a
document.  So whoever saves the latest revision knows how to overwrite
it; if you are behind then you can't save your entry over the latest.

You need to read the latest entry (using `gnus-sync-read') which
currently overrides whatever you've done with the server's state.  I may
make it merge later but it hasn't been an issue for me, I never use two
Gnus concurrently.  Merging is not too bad in any case, you just need to
do a union of all the ranges.

I have the user+password working so now I just need Yamaoka-san to
confirm he won't push gnus-sync.el to Emacs, so we don't break the
Emacs feature freeze.  I'll commit right after.
