From de9f7fa3b08ae0554e57f6a6f5de2559d5bcb871 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ren=C3=A9=20Scharfe?= Date: Sat, 29 Oct 2016 14:55:36 +0200 Subject: [PATCH] commit: simplify building parents list Push pptr down into the FROM_MERGE branch of the if/else statement, where it's actually used, and call commit_list_append() for appending elements instead of playing tricks with commit_list_insert(). Call copy_commit_list() in the amend branch instead of open-coding it. Don't bother setting pptr in the final branch as it's not used thereafter.
