Ugh.  Definitely too ugly if it has to go in every line.  From reading
the docs I interpreted it as affecting the whole example, which would
be far more sensible...

Yes, but we also want to make these really easy for users to cleanly
paste in with minimal effort.  I wonder if a decorator could be
applied to those functions so that nose would then skip the doctests:

def foo()....

but the nose doctest plugin isn't exactly a model of modularity, so
I'm not sure you want to go down that particular road...

The no-prompts option seems to be the cleanest right now.  You may
want then to instead just use a reST block for those, so that sphinx
eventually renders them nicely at least as blocks:

    Plot the window and its frequency response::    ### <<< Added
double colon here

      from numpy import clip, log10, array, bartlett   ### <<< Extra
indent so this is a reST block
      from scipy.fftpack import fft


Just some ideas...
