arraystyle = (:pmatrix|:bmatrix) work incorrectly

[greimel]

When using the pmatrix or bmatrix environments, one needs to omit the alignment instructions like {cc}.

Currently, using arraystyle = :pmatrix produces this

(the ccc shouldn't be there).

Workaround: arraystyle = :round

Thanks for spotting this!

Until #319 goes through, another workaround is arraystyle="pmatrix" (with a string instead of a symbol).
