Actually, looking closer at just what those conditions are: the
giant bit of spaghetti code at lines 177-188 will never enable the
pager if po->html3 is on. Probably that was because of laziness
about counting lines correctly in that case, but anyway it means
the problem situation is unreachable, AFAICS.
It still seems worth fixing in HEAD, in case anyone ever tries to
remove that restriction; but I'm no longer feeling that we need
to back-patch it.
