Currently there is no way to get the userrights of one (or more) certain users directly.
The userrights can be queried from siteinfo[1], but then have to be matched against each user group.
I suggest adding "rights" to "auprop" and "usprop".
And if possible with performance perhaps add "usright" and "auright" aswell to only list users with certain rights.

Rights are done in code (well, as are groups, but group membership is in the database)...
So to do it User::getGroupsWithPermission(), and then just have that override/merge against groups, and do the lookup.
Little faffy, but doesn't seem too bad, I mean, if we're already filtering on groups.
Then for getting rights.. Make sure we pull groups from DB, and then push it through User::getGroupPermissions(), and cache that locally for a bit of saving
Per IRC comment from Reedy:
I mean to get a list of all rights per user, not rights per group.
So a lot like this returns for the current user:

Difference being that it's not for me me but for one or more other users.
