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