From 6bb6b0341af26739ba305b20c62a433f15029049 Mon Sep 17 00:00:00 2001 From: Miklos Vajna Date: Wed, 10 Sep 2008 22:10:32 +0200 Subject: [PATCH] builtin-commit: use commit_tree() First, it adds less code than removes, second this allows us to use recuce_heads() for parents, so that the parents of a merge will be always the same with or without a conflict.
