Comment (by azaozz):

 45067.2.diff is based on 45067.diff and:
 - Removes the whole `url(*)` part from the CSS property.
 - Makes the first regex a bit shorter/faster, and moves the trimming of
 the actual URL to the second regex.
 - A bit of cleanup and some white space fixes (this is a very old
 code...).
