bug in spell

[Spencer W. Thomas]

Spell uses a hash table to determine correctly spelled words.  The
chance of a misspelled word hitting a `1' in the hash table is small,
but non-zero.  Spell will pass many totally garbage sequences of
characters as being spelled "correctly".  It is unfortunate that your
misspelling of "anniversary" gets a hit.  We should note, however,
that spell would run *much* slower if it attempted to look each word
up in a dictionary.
