From a9f5476fbca515171e42a4e06b584a9241341ae9 Mon Sep 17 00:00:00 2001 From: Alban Gruin Date: Fri, 10 Aug 2018 18:51:35 +0200 Subject: sequencer: refactor append_todo_help() to write its message to a buffer This refactors append_todo_help() to write its message to a buffer instead of the todo-list. This is needed for the rewrite of complete_action(), which will come after the next commit. As rebase--helper still needs the file manipulation part of append_todo_help(), it is extracted to a temporary function, append_todo_help_to_file(). This function will go away after the rewrite of complete_action().
