Subject: [PATCH v2 3/5] sequencer: move the code writing total_nr on the disk to a new function

From: Alban Gruin <[email-masked]>
Date: Mon, 7 Oct 2019 11:26:39 +0200

The total amount of commands can be used to show the progression of the
rebasing in a shell.  It is written to the disk by read_populate_todo()
when the todo list is loaded from sequencer_continue() or
pick_commits(), but not by complete_action().

This moves the part writing total_nr to a new function so it can be
called from complete_action().
