No need to apologize: no one can know and remember everything.  I only
remembered that because I recently fixed a bug in Dired which used
that function.

But perhaps our take from this is that file-in-directory-p is not
discoverable enough?  Can you describe how and where you looked for
this functionality?  Maybe if we know that, we could make some changes
to have this function pop up in similar searches.
