+Subject: xtables-translate: don't fail if help was requested
+
+If the user called `iptables-translate -h` then we have CMD_NONE and we should gracefully handle
+this case in do_command_xlate().
+
+Before this patch, you would see:
+
+ user@debian:~$ sudo iptables-translate -h
+ [..]
+ nft Unsupported command?
+ user@debian:~$ echo $?
+ 1
+
+After this patch:
+
+ user@debian:~$ sudo iptables-translate -h
+ [..]
+ user@debian:~$ echo $?
+ 0
+
+Fixes: d4409d449c10fa ("nft: Don't exit early after printing help texts")
