> I had added the function `python-shell-send-block'  twenty days ago in

> prefix "C-u" to call the function will send block without header.

> And I received some feedback that sending a block without a header

> Many python blocks begin with "if condition", and users may want to

> branches.
> 
> So this patch will make sending block without header to be the default
> behavior, and a prefix "C-u" will make the function to send block with
> header.

> Please help review this minor change. Thanks
