[PATCH] IPRange ranges

[Andrew Stribblehill]

control:
  is_chemist = ( IPRange(129.234.12-14) )

goes wrong. The code:

--------item.c:644(ish) in FuzzySetMatch-------------
      for (i = 0; i < 4; i++)
         {
         sscanf(sp1,"%[^.]",buffer1);
         sp1 += strlen(buffer1)+1;
         sscanf(sp2,"%[^.]",buffer2);
         sp2 += strlen(buffer2)+1;
------------------------------------------------------

For the fourth octet which is missing in my match, the sscanf on line
646 returns -1 and buffer remains "12-14".

The following patch fixes this:
