Peter Nelson made an in= terface to spell(1) that showed putative errors in context. I believe it co= uld suggest corrections. I remember the project; I installed hooks for it i= n spell(1).

If there= 's a chance that Peter's program is the one you remember
and you&#= 39;d like to get in touch with him, I can give you his
email address.
