grammatical error; maybe "We've found a non-internal host name; give it more
emphasis."

[Patrick Riordan, 2013/04/03 00:19:00]

As of this patch its only extension host names that we don't provide emphasis
to. chrome:// pages still have emphasis. I thought that if I mentioned that, the
comment would be incorrect if ShouldGreyOutURL is ever used for something
besides chrome-extension.
So I changed the comment to be more grammatically correct, but kept the first
meaning. If you think it's appropriate I can add that currently it's only
chrome-extension:// pages.
