Bug#873434: lintian: Please check for @import ur(http://...) in /usr/share/doc

[Ian Jackson <ijackson@chiark.greenend.org.uk>]

Package: lintian
Version: 2.5.50.3
Severity: wishlist

I have discovered various files in /usr/share/doc/*/html on my system
which do things like this:
  @import url(http://fonts.googleapis.com/css?family=Open+Sans);

Eg,
  /usr/share/doc/python-scipy-doc/html/_static/less/spc-bootstrap.less
  /usr/share/doc/libfreetype6-dev/css/freetype2.css

Please would you make lintian complain about @import url(), or about
fonts.googleapis.com, or something.

Thanks,
Ian.
