[PATCH] gitk: fix for empty line after Comments

From: Pavel Roskin <proski@gnu.org>
Date: Nov 2, 2005, 20:42 UTC
Message-ID: <1130964168.23026.2.camel@dv>

git-diff-tree called with one tree-ish shows the commit ID, which should be ignored by gitk. getblobdiffs() and gettreediffline() recognize and ignore commit ID now.

Also, the p variable that was used as the other argument git-diff-tree is no longer used, so it's dropped in both places.

Signed-off-by: Pavel Roskin <proski@gnu.org>
