Is there some name for the unholy abomination that is the combination of
both styles?:

/* Like this, but without the trailing
 * end-comment on a standalone line. */

I prefer the asterisks on the left because it makes it obvious when
grepping that it's from a comment block; I dislike the standalone
comment for taking up a bunch of room for seemingly no reason.

...Not that I expect to change your mind, or to suggest I've got enough
paint for a shed this large, so any standard is better than no standard...
