From 845839575d37da825746816b24376c7799ef1105 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Mon, 2 Jan 2017 16:26:28 +0100 Subject: [PATCH] sequencer: support a new action: 'interactive rebase' This patch introduces a new action for the sequencer. It really does not do a whole lot of its own right now, but lays the ground work for patches to come. The intention, of course, is to finally make the sequencer the work horse of the interactive rebase (the original idea behind the "sequencer" concept).
