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().
