Unable to edit users in 3.0 beta 1

[numeeja]

Using the latest nightly build, when signed in as an admin user and going into Users -> Authors & users, I am unable to edit user accounts apart from the user I am logged on as.

I can create & delete other users, but there is no option to edit the users. I have tried this on a fresh install and was able to reproduce the same issue. Also the issue has be confirmed by other users.

This appears to be caused by a typo in one of the changes made wrt #13074 - "edit_user" instead of "edit_users". This patch fixes it.

edit_users instead of edit_user capability check. also remove redundant $edit declaration that is identical to one just below

Actually, my patch isn't correct so please ignore it. But the current check ( current_user_can('edit_user', $user_object->ID)) is returning false even for super-admins.

(In [14256]) Explicitly set the capability required in edit_users map_meta_cap branch, so we don't accidentally pass edit_user. props TheDeadMedic. fixes #13074, fixes #13137

The issue still exists in revision [14321]. If you are using multisite and logged in as blog admin (not super admin) the edit_users capability returns false, affecting the edit links on the users page and any plugins that rely on it. Discovered when my admin menu wasn't being added:

add_menu_page('Test', 'Test', 'edit_users', 'test', 'my_output');

This may affect other capabilities as well. Testing...

Actually with further thought this should be expected behavior in multisite as users are sitewide. It just did not function this way in previous versions of wpmu. Time to adjust my plugins...
