The browser displays "behind/ahead/merge needed" only in the tooltip. It should be visible directly on the node so user know which branches require a sync.
Integrated into 'main-silver', will be available in build *201406200001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
