So you mean the code was authored in vim or emacs and then read using a  
WYSIWYG editor? It seems the issue I mentioned with start tags would  
certainly apply here. Other things that are completely equivalent from a  
processing point of view might give trouble too:

   @media only all and (color)
   @media all and (color)
   @media (color)

It is a trade-off. We can limit the amount of valid serializations, but  
that will make hand authoring harder.

I think it is somewhat inevitable that when you use WYSIWYG-mode the  
editor will modify your source code and the way you indent or minimize  
your syntax might get lost. To counter that you could provide syntax  
preferences maybe. So that instead of writing out min-color:1 you would  
write out color. This would have the advantage that existing code would be  
cleaned up using those rules too. This is a general problem however and  
not at all a specific problem with Media Queries.
