use '+' instead of 'or' for bool arrays.

In [8]: numpy.where((a<1) + (b<3), b, c)
Out[8]: array([4, 2, 2, 1])

What's the correct way to do something like this?

a=array( (0,1,1,0) )
b=array( (4,3,2,1) )
c=array( (1,2,3,4) )

where( (a<1 or b<3), b,c)

Python throws a ValueError
I would expect to get an array that looks like
[4,2,2,1] I think


Thanks,
Ross
