 *	Given a printf-like argument list, format it into a work buffer,
 *	append a newline, and send it to the system debugger via
 *	OutputDebugString(). This is probably the only way to do output
 *	from within some other process.
 *
 *	We proactively remove trailing whitespace from the output buffer
 *	and then add a newline. But we don't exit or anything.
