Fix commit e473b7c if an inline file happens to have a line break exactly at buffer limit

The check does only for strlen(line) space and buf_printf will only use at
most space -1 and not print the final character ('\n') in this corner.
Since a missing \n only breaks certificates at the start and end marker,
missing line breaks otherwise do not trigger this error.
