Yes, the patch looked great: simple to implement but return thorough info.
The next question will be how/where to hook it.

Maybe we could setup a flymake backend which looks for (defcustom ... "...")
and things like (re-search-forward "..."), tho maybe hooking it into the
byte-compiler is a better option (that will also make it work with
flymake)
