Thanks Paul, this makes sense.

If it counts, I vote for forcing a conflict ;)

Your example here is actually hitting a very specific edge case as demonstrated by Marcello's
test. As of many versions ago, revisions are generated using a hashing scheme of the document
contents. In your particular case the requests you're issuing contain the same identical data
in such a way that CouchDB will generate a revision of the doc.

Given this, we then have to look at how this plays into replication.
Basically, when we merge the revision trees we get to the case where it's "oh, we already
have this version, cool" because we do already have this version.

Whether or not that behavior is best, or if we should force a conflict if we don't add a leaf
during a write is another question. In other words, the system is working fine, but this particular
behavior can be a bit unexpected.
