       function by Yugal Jindle. Python's `title()` method doesn't work right
       if there are apostrophes etc. in the word, since it breaks words at
       punctuation. According to https://bugs.python.org/issue7008, the
       `string.capwords()` method is also buggy and should be deprecated. This
       is to make "Linda's Tree" not be "Linda'S Tree".
