Separate all operation arguments by commas

[Garados007]

Igor Pro allows omitting the comma at certain argument positions for operations and does allow extraneous commas before the first argument. For example:

// omitting a comma
printf "x=%d, y=%d" 1, 2
sprintf msg, "x=%d, y=%d" 1, 2
// extraneous comma
printf , "text"

I would consider this as bad coding style and propose that all arguments must be separated by exactly one comma and no commas are allowed before or after the argument list.

printf "x=%d, y=%d", 1, 2
sprintf msg, "x=%d, y=%d", 1, 2
printf "text"

Impact

There is a large code base with lots of these coding style errors, so I wouldn't suggest reporting this to WM and fixing their compiler. I couldn't find any case for which fixing the comma leads to a compile error in Igor Pro.
