59 * with a "word" character, because it's the transition from word to
60 * non-word characters that triggers the test for an abbreviation. In

62 * transitions from word to non-word character (or vice-versa) other
63 * than between the next-to-last and last characters of the string,
64 * and there can't be any <blank> characters. Warn the user.
