A query such as https://en.wikipedia.org/w/api.php?format=jsonfm&action=query&titles=Jimi%20Hendrix&prop=revisions&rvprop=ids|timestamp&rvlimit=10&rvstart=20120731000000 returns a query-continue of rvstartid=504924999. According to the API docs, we should just append this rvstartid to the original query: https://en.wikipedia.org/w/api.php?format=jsonfm&action=query&titles=Jimi%20Hendrix&prop=revisions&rvprop=ids|timestamp&rvlimit=10&rvstart=20120731000000&rvstartid=504924999. But this fails because rvstart and rvstartid may not both be used.

Gerrit changeset coming shortly (I need the bug number for the release notes and revision summary).

Version: 1.20.x
