[TxMt] Notification when a open file is updated

[Vincent Tschanz]

Hi,
When I pull a git repository, Textmate update automatically the 
corresponding opened files (which is cool) but it does it silently.
Is there a way to get notified when a opened file is updated?
I found this old ticket about the same issue : 
http://ticket.macromates.com/show?ticket_id=FFEB806B
Is it already implemented or still planned?

Thank you.
