122 * The fts system makes it difficult to replace fts_name with a different-
123 * sized string, so we just calculate the real length here and do the
124 * conversion in prn_octal()
126 * XXX when using f_octal_escape (-b) rather than f_octal (-B), the
127 * length computed by len_octal may be too big. I just can't be buggered
128 * to fix this as an efficient fix would involve a lookup table. Same goes
129 * for the rather inelegant code in prn_octal.
