I think of numpy strings as raw fixed-length byte arrays (since, well,
that's what they are), so I would expect np.zeros to return all-NUL
strings, like it does. (Not just 'empty' strings, which just means the
first byte is NUL -- I expect all-NUL.) Maybe I've spent too much time
working with C data structures, but that's my $0.02 :-)
