Peter Korsgaard	2a053a2430	ar: read_num(): fix reading fields using the entire width ar fields are fixed length text strings (padded with spaces). Ensure bb_strtou doesn't read past the field in case the full width is used. The fields are only read once, so the simplest/smallest solution to me seems to be to just pass the length to read_num() and then zero terminate the string before passing it to bb_strtou. This does mean that the fields MUST be read in reverse order, so some minor reshuffling was needed.
