vi is hashed (/bin/vi)

So, now that I know what I'm looking for: (from the manpage)

    checkhash
       If set, bash checks that a command found in
       the hash table exists before trying to exe­
       cute  it.   If  a  hashed command no longer
       exists, a normal path search is  performed.

fixed by entering shopt -s checkhash

I had this vague memory of bash doing something like this, but I couldn't
find it.
Thanks.
