http://scikit-learn.sourceforge.net/stable/modules/svm.html#kernel-functions

The dev version does list coef0 in that section.

General comment: is there any link to the SVC docstring from the narrative
docs? I couldn't find one, had to go to the "Reference" tab.

http://scikit-learn.sourceforge.net/stable/modules/generated/sklearn.svm.SVC.html#sklearn.svm.SVC

Similarly, it would be nice to have a link back to the first link from the
reference docs.
