Description of problem:

iptables-save cuts space before -j

Version-Release number of selected component (if applicable):

iptables-1.4.7-11.el6.x86_64

How reproducible:
100%


Steps to Reproduce:
---
[root@localhost ~]# iptables -A INPUT -p dccp --dccp-types RESET,INVALID -j LOG --log-level DEBUG --log-prefix "DCCP RESET or INVALID: "
[root@localhost ~]# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         
LOG        dccp --  anywhere             anywhere            dccp RESET,INVALIDLOG level debug prefix `DCCP RESET or INVALID: ' 

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination         
[root@localhost ~]# iptables-save |  grep DCCP
-A INPUT -p dccp -m dccp --dccp-type RESET,INVALID-j LOG --log-prefix "DCCP RESET or INVALID: " --log-level 7 
[root@localhost ~]# 
---

So, there is no space between INVALID and -j, and rule missed after /etc/init.d/iptables save && reboot .

Actual results:
iptables-save cuts space before -j

Expected results:
There should be space before -j

Additional info:
If i manually add space into /etc/sysconfig/iptables all works.
