1.51      millert    63:        Added --csv option to enable processing of comma-separated
                     64:        values inputs.  When --csv is enabled, fields are separated
                     65:        by commas, fields may be quoted with " double quotes, fields
                     66:        may contain embedded newlines.

                     73:        length, substr, index, match, etc., use UTF-8, so the length
                     74:        of a string of 3 emojis is 3, not 12 as it would be if bytes
                     75:        were counted.
