As far as I know, there isn't a way, because the browser will not send any data for an 
input field that is empty in the <form>.

If you want to do that, then you would need some javascript inside the form, which fills 
the empty fields with some "dummy" sequence (like "--empty--"), before posting the form.
Then your module/script would need to catch such fields, and consider them as empty.
