The change had been proposed by me, to correct way too large font sizes.

I tried to answer there, but my mail never appeared on the list of
archived messages, so I try here.
I still think my proposed change is a step in the right direction.
It has to be extended, though.
1.) The function css-expand-length should return always a number in the
same unit of measurement. The percentage cases still calculate
pixels, not points as the other cases.
2.) The callers of this function expect different units of measurement:
css-split-font-shorthand expects point values, css-expand-value
expects characters(?). These usages should be aligned, for example
by using an extra parameter in css-expand-length to indicate in
which unit of measurement the return value has to be calculated.
