[patch 1/4] Make iptables-restore usable over a pipe

[Henrik Nordstrom <henrik@xxxxxxxxxxxxxxxxxxx>]

The attached patch flushes stdout between commands to make output
operations (-L etc) in iptables-restore usable over a pipe. stdio by
defaut buffers output if not connected to a terminal.

Regards
Henrik
