Remember that clients should not be depending on the specific query string
data returned inside the query-continue node, with either the old-style or
new style continuation.
As a partial fix for bug 24782[1], Gerrit change 22742 will cause
action=query&list=recentchanges to start returning rccontinue for
continuations rather than rcstart as it has done in the past. Changes of
this type may be coming to other modules as well as further fixes to bug
24782 are implemented.
