by Geoff Whale. (skip_fields, skip_chars, check_chars): Now size_t, not int. (size_opt): New function. Do not arbitrarily reject size zero. Change the wording of the error message slightly, for convenience. (find_field): Use size_t, not int, to compute sizes. (different, main): check_chars==0 is no longer a special case, as it defaults to SIZE_MAX. (main): Check for overflow with args like -234234234234234. Use 'size_opt' to convert optional arguments to sizes.
