Filipe Manana resolved COUCHDB-1340.
------------------------------------

    Resolution: Fixed

Reduced the limit to 7000 on all active branches and applied the percent encoding of query string values on master and 1.2.x only.

> It was all working until we upgraded some other couches in our replication "web" from couch 1.0.3 to couch 1.1.1. We then set of database and view compactions, and sometime overnight some of the replication links stopped.
> I have curled the command myself, both as a multipart message and a single json response (with header "Accept:application/json" ) and it can be parsed correctly by Python simplejson - I have attached it here aswell - called "troublecurl-redacted.txt" - though it is 18.8mb. The request takes about 6 seconds.
> I don't quite understand why it is reported as invalid JSON? Other reports similar to this that I googled mentioned blank document ids, but I can't see any of these.
