Subject: iproute, batch-cmds, and mac-vlans.

After too much time debugging, I finally realized that the ip
tool was truncating my command because the mac-vlan device name
had a '#' in it.

]# cat /tmp/foo.txt
ru add to 10.99.21.1 iif eth0#0 lookup local pref 11

# IP tool has some hacked up debugging code
]# ip -batch /tmp/foo.txt
  argc: 4
  arg -:to:-
  arg -:iif:-
WARNING:  Using TABLE_MAIN in iprule_modify, table_ok: 0  cmd: 32

So, it acts on eth0 instead of eth0#0, and silently ignores the 'lookup local pref 11'.

I understand that it is trying to parse # as comments, but would you
all be interested in a patch that allowed ignoring '#' except
when it is the first non-whitespace character on a line, and maybe
when preceded by whitespace?  This would of course have the possibility
of breaking someone's script somewhere, so it could be enabled with
a new command line arg, perhaps.

Thanks,
Ben
