i'm presuming that MIN() is the usual macro involving ? : and
that i could probably fix this - tho i have no time at the moment.
8c generally avoids running out of registers rather well, though
i dare you to follow the logic.  as ? : is not common in plan9
code and not highly regarded i guess this case was missed.
