Re: [PATCH] sequencer: finish parsing the todo list despite an invalid first line

Maybe something like

Before the todo list is edited it is rewritten to shorten the OIDs of the commits being picked and to append advice about editing the list. The exact advice depends on whether the todo list is being edited for the first time or not. After the todo list has been edited it is rewritten to lengthen the OIDs of the commits being picked and to remove the advice. If the edited list cannot be parsed then this last step is skipped.

Prior to db81e50724 (rebase-interactive: use todo_list_write_to_file() in edit_todo_list(), 2019-03-05) if the existing todo list could not be parsed then the initial rewrite was skipped as well. This had the unfortunate consequence that if the list could not be parsed after the initial edit the advice given to the user was wrong when they re-edited the list. This change relied on todo_list_parse_insn_buffer() returning the whole todo list even when it cannot be parsed. Unfortunately if the list starts with a "fixup" command then it will be truncated and the remaining lines are lost. Fix this by continuing to parse after an initial "fixup" commit as we do when we see any other invalid line.
