The 3 functions that change letter-case in words, capitalize-word,
upcase-word, and downcase-word work in the same way when moving
forward: they start with the current buffer position.

If you want a function that capitalizes the word at point after
looking back for its beginning, you need to code that using
thing-at-point or some such.
