VS formatting of "file:" string value

Just curious, but why in VS 2008 if I have a line

string str =3D "file:";

are the characters inside the quotes underlined. I couldn't find a font s=
etting like that, and things like http: aren't underlined. Take out the c=
olon, or a use word other than file, there's no underline.
