Most text-files have been commited with LF:
/tmp/ttt/sbml-test-suite> git ls-files --eol | grep "i/lf" | wc -l
   10266
Some have been commited with CRLF:
/tmp/ttt/sbml-test-suite> git ls-files --eol | grep "i/crlf" | wc -l
    1620


The whole repo deserves to be normalized and equipped with a .gitattributes file,
