Well, the point is, we stop advancing kwend when we get to the end of
the keyword, and *vend when we get to the end of the value. If there's
a value, the end of the keyword can't have been the end of the string,
but the end of the value might have been. If there's no value, the end
of the keyword could be the end of the string.
Maybe if I just put that last sentence into the comment it's clear enough?
