I think there is utility to adding a new function or two (my inclination is
to expose broadcast_to in the public API, but leave common_shape in
strick_tricks). NumPy provides all the cools to write these in a few lines,
but you need to know some very deep details of the NumPy API (nditer and
strides).

I don't think more documentation would make this obvious -- certainly
nditer does not need a longer docstring! The best sort of documentation
would be more examples. If this is a recipe that many NumPy users would
use, including it in stride_tricks would also serve such an educational
purpose (reading stride_tricks is how I figured out how strides work).
