See below for an updated patch:
Record a single transaction for conflicting push operations
From: Catalin Marinas <catalin.marinas@xxxxxxxxx>
StGit commands resulting in a conflicting patch pushing record two
transactions in the log (with one of them being inconsistent with HEAD
!= top). Undoing such operations requires two "stg undo" (possibly with
--hard) commands which is unintuitive. This patch changes such
operations to only record one log entry and "stg undo" reverts the stack
to the state prior to the operation.
