[PATCH] Allow gitk to continue and show error message in new repos

From: Alex Riesen <raa.lkml@gmail.com>
Date: Jul 29, 2007, 20:28 UTC
Message-ID: <20070729202840.GA9362@steel.home>

If there is no commit made yet, gitk just dumps a Tcl error on stderr, which sometimes is hard to see. Noticed when gitk was run from Xfce file manager (thunar's custom action).
