I have pulled a fast one here. The !cflowbelow is indeed not so easy to
describe with just a function that creates a list of function names. But
I still think that's a good direction to investigate.

Untested code which won't work. Better:
(let ((org-main (symbol-function 'main)))
(setf (symbol-function 'main)
(lambda (&rest args)
(funcall org-main ...)))))
