The existing code is not great and definitely odd.

This is just a bug fix until such time as it's better.

VELOCITY_PRT is not just used for debugging.

The default is output if MSG_LEVEL_INFO and
there's a control for further output.

This is just fixing Linus' change for KERN_CONT
uses on separate lines from awhile ago.

It'd be nice if a via maintainer actually fixed it.
