From b0a3186140dbc7bd64cbc6ef733386a0f1eb6a4d Mon Sep 17 00:00:00 2001 From: Phillip Wood Date: Mon, 19 Aug 2019 02:18:23 -0700 Subject: [PATCH] sequencer: simplify root commit creation Adapt try_to_commit() to create a new root commit rather than special casing this in run_git_commit(). This significantly reduces the amount of special case code for creating the root commit and reduces the number of commit code paths we have to worry about.
