bug#13305: 24.2; describe-function gives incorrect function location information (for functions changed in a hook?)

[Stefan Monnier]

BTW, now that `defun' is macro-expanded when loading the file (thanks to
eager macro-expansion), we could actually use it to record the file where
this `defun' was found, even if that `defun' is (as in your case) only
executed at some later time.
