[wp-hackers] button patch for comment post section

[Kristian Gavran]

Hallo all,

my Name is Kristian Gavran and I'm transisting my homepage from a 
selfwritten simple CMS system to wordpress.
I make good progresses, the transition is already complete. Along the 
transition I've found an annoying point in the comment post section.
When the user forget to fill in all the needed Information just a simple 
error message appears.

I thought that a small "Go back and try again" Button on the bottom of 
the error message would be a good Idea.
So I've made a small patch adressed to this issue. Maybe you find it 
usefull and can commit it. (I have to admit that this is my first patch 
to an open source project. So when somthing is not ok or you have some 
suggestions, please tell it to me, so that I can make it right :-)

Maybe later when I have some time (and nobody else do it ;-) I will try 
to intigrate this (or maybe all?) error messages into the existing 
templates system of worldpress.

   -Kristian
