#1574: std.syslog creates empty syslog entry
----------------------+--------------------
 Reporter:  kipusoep  |       Type:  defect
   Status:  new       |   Priority:  normal
Milestone:            |  Component:  vmod
  Version:  4.0.1     |   Severity:  normal
 Keywords:  syslog    |
----------------------+--------------------
 I've experienced this on a clean installation of Debian (7.6.0, amd64)
 with the latest Varnish v4.0.1 release.

 Calling std.syslog creates an empty entry in the syslog, for example by
 using:
 std.syslog(180, "Test");
