There's a difference between enforcing our coding style on new code,  
and retroactively applying our new style to the hundreds of thousands  
of lines of code that already exist.  Your comment conflates these two  
issues.   No-one is going to disagree that we should enforce the  
coding style on new code.  That would be stupid.  However it is clear  
that applying our current coding style to existing code is a much less  
clear-cut issue.  We wouldn't be having this discussion if it were as  
obvious as your comment suggests.

There's also a huge difference between enforcing WebKit coding style  
and enforcing some other coding style.  Trailing whitespace is not  
mentioned in the WebKit coding style guidelines.
