Using `git-annex version: 4.20130802` on Debian unstable, when trying to add the feed at <http://www.ndr.de/fernsehen/sendungen/extra_3/videos/zum_mitnehmen/extradrei196_version-hq.xml>, I get:

[[!format sh """

(Oh, and using `format` with nono-ASCII seems to break down., at least in the preview.)
