    I needlessly complicated things here.  All I wanted to say is that the
    display engine handles

    (defface face nil
       "Nil face.")

    (put-text-property (line-beginning-position) (line-end-position) 'face 
'face)

    and

    (put-text-property (line-beginning-position) (line-end-position) 'face nil)

    much the same way.

In that case, maybe the `face' custom type should accept nil
as an alternative.  That way, the existing default for
delphi-other-face would be valid, it would still work the same
as now, and it would not require changing the :type spec.

Does anyone see any problems with that?
