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

[Syohei Yoshida]

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.
