I don't have a big problem with that. But what "compatibility" is = gained? Compatibility of what with what? This is a new variable. =20 > Since this is a new defcustom woulddn't it be better to not let nil be > a valid value? That may catch some problems and the backward > compatibilities are not likely to be big. I agree with Lennart here. KISS. I see no reason for nil. I am unaware = of any backward compatibility issue for this variable.
