I defer to your opinion on this, since you know more about it than I
do. But I think it would still be worthwhile to write a quick Perl
script and calculate the number q-grams in various sample texts for
various values of q. The worst case is surely exponential in q, so
it'd be nice to have some evidence of what the real-world behavior is.
