ddb81e5072 (rebase-interactive: use todo_list_write_to_file() in edit_todo_list(), 2019-03-05) made edit_todo_list more efficient by replacing transform_todo_file with todo_list_parse_insn_buffer. Unfortunately, that innocuous change caused a regression because todo_list_parse_insn_buffer would stop parsing after encountering an invalid 'fixup' line. If the user accidentally made the first line a 'fixup' and tried to recover from their mistake with `git rebase --edit-todo`, all of the commands after the first would be lost. To avoid throwing away important parts of the todo list, change todo_list_parse_insn_buffer to keep going and not return early on error.
