Changelist:

20071119 -
  - Add nongreedy tokenizer. Same semantics of strtok_r(), but doesn't skip
    empty tokens.
  - Renamed tokenizer to split, since really that's what it was doing.
  - You can invoke the nongreedy tokenizer by using '?' as the first character
    of a {} set:
     args: :{?4,6}
     input: one:::four::six
     output: four:six
