Showing your test cases would be helpful, so we can see exactly what you've
tested.

One thing I notice right off the bat is that your function
insert-everywhere/in-all-words doesn't fulfill the stated contract.
In particular, the else clause doesn't return a list of words.
(consing a list of words on to a list of words doesn't yield another list of
words.  You probably meant to use append.)
