Clef to Key Signature distance

[Walter Hofmeister]

Hello,
    I am trying to change the distance between the clef and the key
signature as I like the look if they are closer together. In the past I have
used this tweak:

\override Staff.Clef   #'space-alist = #'( (staff-bar minimum-space . 3.7)
(key-signature minimum-space . 3.0))

This no longer seems to work and I can't seem to get anything to change this
distance. I have tried the following:

\override KeySignature #'space-alist = #'((time-signature extra-space . 0))
\override Clef   #'space-alist = #'( (staff-bar minimum-space . 0)
(key-signature minimum-space . 0))

Even the extreme values of zero have produced no change in the output.

Any ideas?
TIA
