It is?  What about when the difference between the two is an odd
number of multibyte units?  Writing to *midpoint_pointer after
setting it up in such a fashion is going to corrupt some data
(unless, of course, you *want* to modify the last byte(s) of one
unit and the first byte(s) of the next ;')

>(what's the average of the 7 clubs and the 9 clubs?)

More to the point, what's the difference between the 7 clubs and the
8 clubs?

Perhaps you mean that it is an *allowed* operation, without regards
to the wisdom of same.  Or perhaps you guys are only talking about
char pointers (and then what happens if you run into a multibyte char
machine?).
