Replace a misguided test with a valid one

The code had min and max of an integral type and tested min + min / 2,
which naturally overflowed, provoking a compiler warning.  The test
was meant to be testing min - min / 2; but min is even, so this is
just min / 2; and doubling that won't overflow (which is what the test
is about).  As it happens, min + min / 2 is in fact max - max / 2,
which *would* be a good value to test, since max is odd.  So add a
test for that and remove the broken test.
