'format-patch' could fail due to reasons such as out of memory. Such failures are not detected or handled, which causes rebase to incorrectly think that it completed successfully and continue with cleanup. i.e. calling move_to_original_branch Instead of using a pipe, we separate 'format-patch' and 'am' by using an intermediate file. This gurantees that we can invoke 'am' with the complete input, or not invoking 'am' at all if 'format-patch' failed. Also remove the use of '&&' at the end of the if-block, and rearrange the 'write_basic_state' and 'move_to_original_branch' to make the logic flow a bit better and easier to read.
