The current message is "bisecting %s" (or "bisecting branch %s"). "%s" is the current branch when we started bisecting. Clarify that to avoid confusion with good and bad refs passed to "bisect" command. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
