A good point.  Perhaps what we really want, then, is this:

umath.bitwise_and = the C (or Python) operator, &
umath.logical_and = the Python 'and' operator

etc.

After reconsidering it, it seems that a logical_and that returns only a 0 or 1
doesn't have any significant advantages over Python's 'and', which can be used
to selectively evaluate a construct, return the truth value of the logical
and, or to selectively give a return value for the last true argument.
