The line from the corner of the bridge appears to be a finish crack, which is limited to the finish only and not the underlying wood. These have been called "whisker cracks," there is a lengthy thread in the UMGF on the subject. One of my five Martin's have them (2009 D-28), on all four bridge corners. It may be caused by the routing and installation of the bridge process, see the UMGF thread for details.

edit - I did not know the UMGF thread was closed, click on the link from bobby b's post below.
