Harvey, please remember the whole %p<foo> concept is based on
modifier after format specifier.
I think %p6 followed by combinations of things:
"::" compressed v6, largest block of consecutive 0's replaced with ::
"-:" no separating colons, use space instead
"-0" no leading 0's
".4" last word as ipv4 dotted decimal
"x1" u8 form
"x2" be16
"x4" be32
"x8" be64
So that you could have:
%p6:: 1234:000a::c0a8:0101
%p6::-0 1234:a::c0a8:0101
%p6::-0.4 1234:a::192.168.1.1
%p6-0-:x1 0 1 2 3 4 5 6 7 8 9 a b c d e f
%p6x1 00:01:02:03:04:05:06:07:09:0a:0b:0c:0d:0e:0f
etc. If acceptable, I'll submit a patch.
