Assets with title that contain "-- text --" break File Check when they match in the results table

If an asset page name contains the following "-- text --" which happens to be the case for any asset in this group: http://www.curriki.org/xwiki/bin/view/Group_MathForAmerica--Geometry

Particularly when the resource also as "--" in its name like the sub assets here:

http://www.curriki.org/xwiki/bin/view/Coll_Group_MathForAmerica--Geometry/Units_0?bc=;Coll_Group_MathForAmerica%2D%2DGeometry.GeometryCurriculum

File check gives a velocity error.
