Hello, Ivan.

The following patch is a first attempt to fontify parameter packs. After
applying it, please be sure either to recompile CC Mode entirely, or
first to compile cc-langs.el (which contains macros), and then all three
of cc-fonts.el, cc-engine.el, and cc-mode.el.
It seems to fontify the "Y" above OK. I've tried it on a stock example
out of Wikipedia, and that works. Could you try it out on your code,
please, and let me know how well it works.
Here's the patch:
