That looks quite weird, maybe we should introduce another mode for this, and
only this, case?

FWIW, I've been recently reminded that:

	/*
	* This is the preferred style for multi-line
	* comments in the Linux kernel source code.
	* Please use it consistently.
	*
	* Description:  A column of asterisks on the left side,
	* with beginning and ending almost-blank lines.
	*/

except in net/ and drivers/net/ where the style in this patch is used.
