Indeed.  Not only does this form avoid the magic numbers, increase
readability, and abstract the representation, it fixes the error I made
in my code.

It turns out that my code worked by fluke: checking spaces.  I should
try not to post late at night.

I read your message after Eric Abrahamsen's, which echoed your point.
Taking the advice paid off handsomely!  Thank you.

I posted `buffer-most-used-words-4' and an indication of its performance
in a follow up to Eric Abrahamsen's message.
