How modify refill-mode's desire to remove hard returns from text???

[Christian Seberino]

I need refill-mode's feature of constantly reformatting
text when I type new characters.

But, I don't want it to eliminate hard returns in order
to make lines be filled up more.

I cannot type short lines

like
this 
right
here.

Can I fix this?

P.S. My main goal with refill-mode is the strengthen auto-fill-mode
so hard returns are *added* more often when necessary.  I never
want to *remove* hard returns however.
