'All Groups' link has wrong url

[dwenaus]

in the file bp-themes/bp-default/groups/index.php
on the line
<li class="selected" id="groups-all"><a href="<?php bp_root_domain() ?>"><?php printf( __( 'All Groups (%s)', 'buddypress' ), bp_get_total_group_count() ) ?></a></li>

bp_root_domain()

should be:

bp_get_root_domain() . '/' . BP_GROUPS_SLUG

this is not a big deal because all the action is happening with javascript which ignores the url. however the link is incorrect - and if someone were to copy the url for use as a direct link, it wouldn't work.

patch is tested and works
