Paul Joseph Davis resolved COUCHDB-357.
---------------------------------------

       Resolution: Won't Fix
    Fix Version/s: 0.9.1
         Assignee: Paul Joseph Davis

Given the set of keys: [1, 0] [1, 1] [1, 2] and a group_level=1 then we'd need to provide the equivalent of key=[1] but this will fail during reduction because startkey=[1]&endkey=[1] (the equivalent of specifying key=[1]) will select no keys.

> If you try and execute a multi-key reduce view with a group_level param, could returns a query parser error with message '"Multi-key fetchs for reduce view must include `group=true`".  The error persists if you add that param.  The problem appears to be that couch_httpd_view.erl is only checking for 'exact' grouping, not an integer level.  Attaching a patch; thanks to Paul Davis for the direction...
