  # First regex truncates to the length, plus the rest of that word, if any.
  # Second regex removes any trailing whitespace or punctuation (except ;).
  # Unlike the regular truncate method, this avoids the problem with cutting
  # in the middle of an entity ex.: truncate("this & that",9)  => "this &am..."
  # though it will not be the exact length.
