special file slow in ods-syntax-check,
I have a funny issue with a neat simple file ilog.gnumeric which boosts the execution time of t6150-ods-syntax.pl by three minutes if it is put in samples as test file. Strange as the original sample calculating about twice as many ilogs finishes without delay. The output in the terminal window stalls with display of 'Checking ../samples/ilog.gnumeric (strict conformance)' and 'Checking ../samples/ilog.gnumeric (extended conformance)'.
