Thank you, I have pulled this in and will expose it to -next testing.

Results from "make run":

198 test(s): 198 passed, 0 skipped, 0 failed => status: success

Results from "make user":

198 test(s): 196 passed, 2 skipped, 0 failed => status: warning

I don't understand the "warning" given that the "run.out" file has all
"OK" aside from the two "SKIPPED" tests. Or maybe I am just forgetting
how this works. ;-)

Thanx, Paul
