From c8e4159efd226218d827b5da71fc8f95f8172412 Mon Sep 17 00:00:00 2001 From: Han-Wen Nienhuys Date: Fri, 21 Aug 2020 16:59:35 +0000 Subject: [PATCH] sequencer: treat CHERRY_PICK_HEAD as a pseudo ref Check for existence and delete CHERRY_PICK_HEAD through ref functions. This will help cherry-pick work with alternate ref storage backends.
