netstat -iW strip interface name to 7 symbols

[Mykola Dzham]

I use ifconfig vlanXXX name ... for setting interfaces names that make
sense for me (for example name of parity on remote side on this link).
But when i run netstat -iW interface names striped to 7 symbols, though
"If -W is also present, print interface names using a wider field size".
I think that 7 symbols is not enough wide: ifconfig ... name allow up
to 16 symbols. Attached trivial patch expand interface name field to 16
chars, but my question is "is 7 symbol length is set specially?"
