/* The C Programming Language, 2nd Edition
*
* Exercise 1-11: How would you test the word count program? What kinds of
* input are most likely to uncover bugs if there are any?
*
* Answer: New lines (such as those caused by wrapping text) are most likely to
* introduce erroneous word counts, as well as symbols that are strung together
* but don't create actual words.
