It's unclear who did the "[Make change minimum.." alteration.

I do it this way:
[hirofumi@...l.parknet.co.jp: make change minimum, don't call d_move() for dir]

Also, who was the primary author of this patch?  It *looks* like it was
Al, unsure.  If it was indeed Al then this can be communicated by
putting his From: line at the very top of the changelog body.
