From 542e165cdc4fbebbfe7c8954ca1aa1d4162e38cb Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 28 Mar 2007 13:33:37 -0700 Subject: [PATCH] Fix "--pretty=format:" for parent related items. There are two breakages in the %P/%p interpolation. It appended an excess SP at the end of the list, and it gave uninitialized contents of a buffer on the stack for root commits. This fixes it, while updating the t6006 test which expected the wrong output.
