add_role(), capabilties.php typo otherwise plugins might not work as expected

[nielshackius]

In wp-includes/capabilities.php
in line 325
is:

return $wp_roles->add_role($role, $display_name, $capabilities = '');

but really should be, since capabilties is really set locally by the functions

return $wp_roles->add_role($role, $display_name, $capabilities);

If not: The third argument of add_role won't work as expected.

The third argument is intended to be optional. See how it is used in populate_roles_160() in wp-admin/upgrade-schema.php.

Yes, but this is a call, not a function definition, Ryan ;) Valid bug.

This is low-hanging and needs a quick fix.

If I could read, I might be dangerous. :-)
