6    written it more tidily in the first place. Will I ever learn? It has grown and
7    been extended and consequently is now rather, er, *very* untidy in places.

2229    
2230          Complication arises in the case when the newline option is "any" or
2231          "anycrlf". If the previous match was at the end of a line terminated by
2232          CRLF, an advance of one character just passes the \r, whereas we should
2233          prefer the longer newline sequence, as does the code in pcre_exec().
2234          Fudge the offset value to achieve this.
2235    
2236          Otherwise, in the case of UTF-8 matching, the advance must be one
2237          character, not one byte. */
