    doc/man3/ASN1_STRING_length.pod: cleanup NUL byte non-guarantee paragraph

     - Replace "null" bytes with "NUL" (as spelled elsewhere).
     - Use proper formatting for "IA5String", "BMPString", "UTF8String".
     - Add missing punctuation.
     - Minor rewording with respect to Unicode encoding.
