I have the impression that the question is aimed in my direction, but
I don't understand it enough to answer. E.g. I don't understand what
you mean by "find-file-at-point returns a list of relative
file names" and how it's relevant to the discussion.
Maybe the answer you're looking for is something like:
(pcase-let ((`(,start . ,_)
(completion-boundaries <str> <collection> <pred> ""))
(compls (all-completions <str> <collection> <pred>)))
(if (zerop start) compls
(let ((prefix (substring <str> 0 start)))
(mapcar (lambda (compl) (concat prefix compl)) compls))))
