[wp-testers] Missing "?>" tag in "wp-config.sample.php"

[Kirk M]

An excellent explanation, Andy...thanks! Obviously I've been one of 
those "PHP must be balanced" type folks. Didn't know about the blank 
lines under the closing tag either. I need to mark this particular 
message in my email for reference for when my old(er) brain fails to 
recall this correctly. Happens more and more often these days. :P
I'll also add the comment in my "wp-config.php" file like you suggested.
