NSCA Confusing host check results as service checks

[Sloane, Robert Raymond]

It looks like the problem is caused by using "," as the delimiter.
There is a "," in the status string "PING OK..." which would provide
NSCA with the fouth argument, and make it a service result rather than a
host result.
