zero suppression vs compression in addresses

[Alan Batie]

I think I may have misinterpreted how zero compression and suppression
work:  when I say 2607:f678:1::0/60, I expect the "::" to mean "all 0's
from the preceding digit to the next", but from what I'm seeing
configuring things, (leading) zero *suppression* seems to be happening
at the same time within word (32 bit) boundaries, which colons always
delineate, making that really 2607:f678:0001::0/60.  Thus what I really
wanted to say was 2607:f678:1000::0/60.
