The stop list dates back at least to V7 spell.  Unfortunately, it's not
a solution to this problem.  The difficulty is that there are far more
wrong words than right ones.  /usr/dict/words lists only "sincere", but
spell will accept "sincerly", "sincerement", "sincereness", "sincered",
"sinceres", and "sincereless" (again, I checked).  I admit that some of
these (notably -ment and -less) are not likely typos.  However, the "-d"
and "-s" forms are one-keystroke errors, and the "-ness" form can easily
be generated by a person who has momentarily forgotten the word "sincerity".
(Which worries me, BTW:  there aren't many words ending in "e" that can legally
have -ity added to them, but spell takes "sincerity"...)

The end result is that, if every possible typo were placed in the stop
list (a nontrivial task), the hashing scheme used would probably begin to
break down (though I haven't calculated the probability of this).
