Code Style: Ensure that each operation argument is separated by a comma

Igor Pro does allow omitting the comma between the first and second
argument of an operation and also allows adding extranous commas before
the first argument.

This isn't considered as good coding style [1] and allowing this does
also makes the Igor grammar [2] more complicated than needed.
