Blogger's latest comments fix

You can use Blogger's comments feed as a "latest comments" widget for your blog at blogspot.com. This pipe removes the "?showComment=" substring from comments feed's urls, to prevent the passage of page rank to duplicated pages. EXAMPLE: Each element of the standard Blogger's comments feed has the following structure: http://exampleblog.blogspot.com/2008/05/post-permalink.html?showComment=1234567890#c0987654321; this pipe will change it to: http://exampleblog.blogspot.com/2008/05/post-permalink.html#c0987654321
