Used by the routines at 30706 and 30739. On entry, B holds 3 when checking whether it's worth ANGELFACE raising his fist (30706), or 2 when ERIC or ANGELFACE has already raised his fist (30739). Returns with the carry flag reset if anyone was hit or is within hitting range, and D holding that unfortunate character's number.
