[pymvpa] An error occurs when I use the function "zscore" ...

[Yaroslav Halchenko]

our bad -- documentation lied -- apparently std needs to be an array
whenever pervoxel is True (which is the default).

I will patch it up in 0.4.x series (I don't think mvpa2 is prone to it -- will
check too), meanwhile just specify std with an array explicitly

 std=N.ones(dataset.nfeatures)

Cheers and thanks for the report
