i created my syntax file for my gvim long time ago, i have setup the
comment section of my code to be underlined. recently, i found the
underlines to be annoying, and trying to get rid of these underlines,
but i have no idea how the underlines got there in the first place, and
i am having problem trying to getting rid of them.

does anyone have any ideas? what to look for in the syntax file to try
to get rid of these underlines?
