The spec has explicit instructions for how to serialize gradient
functions <>.

Or rather, it *would*, if I hadn't mucked up something when I
committed last night.  Looks like I've uncovered a bug in the spec
formatter.  For now, check out
<> and look near
the bottom for the gradient serialization algorithm.

Short answer: the spec currently requires that gradient to be
serialized as "linear-gradient(top, black, white)".
