Subject: liboconfig: Allow the argument list of blocks to be empty.
X-Git-Tag: collectd-4.3.0beta0~28
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=c9230a2d9fb5cb7557edaf92cf3acd75d9573bf0;p=collectd.git

liboconfig: Allow the argument list of blocks to be empty.

This way the `<Threshold>' block doesn't need a bogus argument just to make the
parser happy.
