Hi everyone!

Here's one more patch for another "missing space in save() function"
bug. This time it's the "tos match" userspace extension. An inverted
TOS match is not saved correctly, so that iptables-restore would
understand it.

The patch is a bit longer because it tidies up save() as used by
iptables-save without adding white-space in print() as used by
iptables -L.

Michael
