I did this to avoid repeating the filename in all tests. However, the exported symbol seems to suggest you want to use this somewhere else, but grep didn't give a clue where, maybe you have local changes still to be submitted?. If this is a problem in the future, test cases were this behaviour is not wanted could start with a special character (like a colon) to indicate that following lines don't want the filename appended to each command and are to be passed raw to the compiler.
