PATCH: Add printing of the style to zstyle+ through option -p

[Sebastian Gniazdowski <sgniazdowski@xxxxxxxxx>]

Hello,
I think that many of us often dreamed about omitting the output
parameter and the following print when checking out a value of style:

zstyle -s :the:style:path style the_parameter; print $the_parameter

I've stumbled upon the interesting function zstyle+ and I thought
about adding an option -p to it that would print the style:

zstyle+ -p :the:style:path style

The simple patch adds the option.
