... that was fast...

    Add the -g option, causing IPv4 output in verbose mode to be on one line.

... I was having a look at print-ip.c to see how "-v" is passed down,
stumbled over "ndo_gflag" and was very confused to see functioning "-g"
code in there... and then I looked at git log ;-)

So - will take that into account for print-ip6.c
