[RFC] Documentation/CodingStyle: Add rules for goto labels

[WANG Cong <xiyou.wangcong@gmail.com>]

There are many people use Lindent to indent their code, but Lindent gets wrong when it
meets goto labels. This should be fixed manually. 

And kernel's CodingStyle doesn't specify the indentation for goto labels explicitly.

This patch adds specifications on those things about goto labels in CodingStyle. And it is 
against -rc3 source tree.

Any advice or comments are more than welcome!

Regards!

 Don't put multiple assignments on a single line either.  Kernel coding style

 Outside of comments, documentation and except in Kconfig, spaces are never
 used for indentation, and the above example is deliberately broken.
