No backlink in comment error messages

[doktorbro]

If a commenter press "Post comment" but forget to leave name, email or comment, he gets a white screen with an error like: "Error: please type a comment."

The shocked user thinks: "What now? Am I stupid? Is this the White Window of Shame?"

The answer is always: "Go back and try it again." That's why we need to put that obvious hint: "Back" by default. It's so easy to be friendly :-)

I agree, we have to change the white screen. The "Back" link is a nice start but we need to allow users to change the error message the page design.

Yes, design is important. But the "Back" link only is a huge step. Start it, please. All you have to do, is change

wp_die( __('Error: please type a comment.') );

to something like

wp_die(  __('Error: please type a comment.') ,
__('Error: please type a comment.') . ' | ' . get_bloginfo ( 'name' ),
array( 'response' => 500, 'back_link' => true ) );

I think it would be better if we came up with a way to easily leverage comment_form() presence and return a friendly, theme-wrapped error message.

This is likely a duplicate of other tickets, in that case.
