Description:
Consider the following queries:

• http://test2.wikipedia.org/w/api.php?action=query&list=allusers&augroup=reviewer&aufrom=Selenium_user&aulimit=1&auactiveusers=1
• http://test2.wikipedia.org/w/api.php?action=query&list=allusers&augroup=reviewer|editor&aufrom=Selenium_user&aulimit=1&auactiveusers=1
• http://test2.wikipedia.org/w/api.php?action=query&list=allusers&augroup=reviewer|editor|qa_automation&aufrom=Selenium_user&aulimit=1&auactiveusers=1

As you can see the value of recenteditcount is x in the first query, 2x in the second query and 3x in the third query. My guess is that the first one returns the correct value, while the other two multiply it by the number of queried (with augroup) groups that Selenium_user belongs to.

Now consider the following query:

• http://test2.wikipedia.org/w/api.php?action=query&list=allusers&auprop=groups&aufrom=Selenium_user&aulimit=1&auactiveusers=1

The value of recenteditcount is now 4x, which I guess is the number of the groups that augroup could accept and that Selenium_user belongs to. The fact that augroup is used or not doesn't influence the result in this case.

I think the value of recenteditcount should be x in all the above queries.
