Log:
add test for differences in extra kerning pairs

Currently, all Italic fonts have the same extra kerning pairs
(with a different numerical value, of course); all upright fonts
have the same extra kerning pairs. Italic fonts have several
kerning pairs for Greek that are missing in the upright fonts.
