Ah!  Well, I was using isc-dhclient-4.3.1 (on Debian Jessie) and I know
this ignores the router advertisements because I use it to test DHCPv6
servers without router advertisements.  So I've switched to an Ubuntu
17.04 machine with isc-dhclient-4.3.5 and that shows similar behaviour
to dhcpcd: a /128 DHCPv6 address and route entries for both the /64 and
the specific DHCPv6 address.  But it doesn't pick up a SLAAC address so
there might be something else misconfigured.

Unfortunately, I don't have a router that I know to be correctly
configured to test against and compare with.
