 There appears to be a bug in iter_split or nt_finder.

 Sample code:
 #include <iostream>
 #include <string>
 #include <vector>
 #include <boost/algorithm/string.hpp>

 int main() {
         std::string str("Hello, world, !!!");
         std::vector<std::string> slist;

         boost::algorithm::iter_split(slist, str,
 boost::algorithm::nth_finder(", ", 0));

         for(int index=0; index<str.length(); ++index)
                 std::cout << slist[index] << std::endl;


         return 0;
 }

 Output:
 Hello
 world
 !!!

 Expected Output:
 Hello
 world, !!!

 All other indices seem to work, only when you use 0.

 This also happens on boost 1.37.0, so its possible it could be in every
 version in between.
