Mutates the given doc by adding a _revisions property.

[jemc]

When I pass a doc to put, it does not mutate the doc, and I can use it again expecting it to be the same. When I pass a doc to validatingPut, it mutates the doc by adding a _revisions property.

I'd like to be able to pass an doc to validatingPut without it mutating the doc.

EDIT: Same goes for validatingBulkDocs and others.

Thanks for reporting. Yes, it should copy the document before modifying it. (The modification itself is in line which CouchDB's behaviour, but it still shouldn't modify input.)

If anyone wants to work on this (it should be a relatively simple matter of modifying/adding an extend() call), keep an eye on pouchdb/pouchdb-server#143 ; this repository is probably going to be deprecated in favour of that one soon.
