From fe1230dece81450004d02fa8a470f8dab8f7fdd9 Mon Sep 17 00:00:00 2001 From: Lars Hjemli Date: Thu, 24 Apr 2008 23:32:02 +0200 Subject: Integrate diffstat with diff This creates a generic diffstat function in ui-diff, which then is invoked from cgit_print_diff with the result that both commit and diff- view gets a diffstat.
