[cmake-developers] syntax of '_' should be treated as symbol

[Guillaume Papin]

I tested your patch and that is indeed how I expect cmake-mode to work. The current behavior has always been surprising compared to other Emacs modes.

I hope this get added to CMake,
Guillaume

I created git animations about this patch. Please see them.
Original version does not stop at underscore by word commands such as
forward-word. On the other hands, fixed version stops at underscore.
This behavior is same as other major-modes.
