Integrate pasted explanation of GPLv2§2(c).

GPLv2§2(c), so this pasted text is as good as any that I could think of,

because the latter section requires so much attention, it seems
appropriate to get the less complex parts of GPLv2§2 out of the way
before diving into that essential discussion of GPLv2§2(b).
