Subject: list: Avoid space in front of the first argument.
X-Git-Tag: 005~54
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=7aa696d1a8253b31a1973b01f34911818d1f7110;p=network.git

list: Avoid space in front of the first argument.

When the first argument was added to an empty list, there
was a leading space character which looks ugly.
