wrong URL form for multiple files
I get
Multiple files for 'topologicalgroup' in repo 'topology' for 'en':
/Users/kohlhase/localmh/MathHub/smglom/topology/source/topologicalgroup.de.tex:1
/Users/kohlhase/localmh/MathHub/smglom/topology/source/topologicalgroup.en.tex:1
there should be a colon at the end of each line here.
