I mainly played dnd 3.5, but sometimes my friends talked about the older versions (3.0, 2, ...). You very well know some of them .
I referred just to the bison's sizes. Sorry for the not so specific quoting.
I think the rules are straight about the spell spacing. YOU MUST ALWAYS PLAY IT TO A GRID INTERSECTION. Of course you can house rule it. See the main FAQ about the POO of turning undead: "Like a burst, the effect expands from the point of origin (which must be a grid intersection of the turning character’s space) out to a maximum distance from the point of origin."
