pppd's defaultroute option

[Mouse <mouse%Rodents-Montreal.ORG@localhost>]

It appears to me that pppd's defaultroute option simply doesn't work
for IPv6, nor do I see any v6 analog of it.  Is there some reason for
this?  It's annoying to have to install a default route in ipv6-up
when, as far as I can see, there's no reason pppd couldn't do it for me
just as easily as it does for v4.

The system I care about at the moment is 4.0.1, but based on the
manpages this appears to be just as true on the other two versions I
run myself (5.2 and 1.4T) and according to a guest account I have on a
system which reports itself as 6.1_STABLE.
