From cbef27d61cd6ae4f1ecae054eb9df06e898148d8 Mon Sep 17 00:00:00 2001 From: Alban Gruin Date: Tue, 29 Jan 2019 16:01:47 +0100 Subject: sequencer: refactor transform_todos() to work on a todo_list This refactors transform_todos() to work on a todo_list. The function is renamed todo_list_transform(). As rebase -p still need to check the todo list from the disk, a new function is introduced, transform_todo_file(). It is still used by complete_action() and edit_todo_list() for now, but they will be replaced in a future commit. todo_list_transform() is not a static function, because it will be used by edit_todo_list() from rebase-interactive.c in a future commit.
