Error when saving with outdated _rev value

[berb]

Hi, I ran into this problem, that might be relevant for other users as well:

1. Create document with couch-client, receiving _rev 1-X
2. Change document NOT with couch-client, i.e. by using Futon, resulting in _rev 2-Y
3. Call save() again from couch-client. => Will NOT cause error in callback, but faulty doc (_rev undefined).

The actual CouchDB response to the bulk_docs POST contains the appropriate error (conflict), which is not handled by couch-client however.

I'm using CouchDB 1.0.2, couch-client 0.0.4 and node.js 0.4.7

Thanks for your help! Greets
