REST API limits number of results to 10

I'm using the REST API to get the wiki users as per the example in
http://platform.xwiki.org/xwiki/bin/view/Features/XWikiRESTfulAPI
i.e.

http://<server>/xwiki/rest/wikis/query?q=object:XWiki.XWikiUsers

This only returns 10 of the users in the wiki database. If I make the call using curl, it returns 10 non-hidden users. If I make the call from a browser, it returns almost the same set of 10 users except that 2 of them are replaced with hidden users.

A workaround is to use the start and number parameters to the query and then repeat the call incrementing the start parameter until nothing is returned.
