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

*
* 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.
