Robert Newson commented on COUCHDB-711:
---------------------------------------

I think it does make sense. The Etag is calculated from the document, attachments and history of the item, so the ETag for the document will be the same value as for all of its attachments.

This patch adds consistency since you already get the Etag header in other PUT cases. With this patch, a client can expect Etag on all responses (GET, PUT, DELETE) and all modifications (PUT, DELETE) can supply its value in an If-Match header.
