[PATCH] coding-style.rst: Add fallthrough as an emacs keyword

[Joe Perches <joe@perches.com>]

fallthrough was added as a pseudo-keyword by commit 294f69e662d1
("compiler_attributes.h: Add 'fallthrough' pseudo keyword for switch/case use")

Add fallthrough as a keyword to the example .emacs content
so emacs can colorize or highlight the uses.

 That's OK, we all do.  You've probably been told by your long-time Unix

 This will make emacs go better with the kernel coding style for C

 Va bene, li facciamo tutti.  Probabilmente vi è stato detto dal vostro

 这会让 emacs 在 ``~/src/linux-trees`` 下的 C 源文件获得更好的内核代码风格。
