I generated this by running:
find ./ -type f -exec sed -i 's/ghelp:fdl/help:fdl/g' {} \;
By updating the translations at the same time, it should be easier on
the translators as there's no reason to invalidate these strings.

[Mike Fleetwood: Explain the underlying cause and distro versions.]
This gnome-desktop commit, first included in version 3.5.5, switched the
package from using gnome-doc-utils to yelp-tools so changed the
installed location of the GNU FDL license file from
/usr/share/gnome/help/fdl/C/fdl.xml to
/usr/share/help/C/fdl/index.docbook, thus changing the yelp URI from
'ghelp:fdl' to 'help:fdl':
