Separate UDF Formating from Built-in in "Function Calls"
We cannot treat UDF parameter listing/indentation in similar vein to Stored Procedure call formatting. All "Functions", be they UDF or built-in, are lumped into the same four RESTRICTIVE options on the "Function calls" page, and we have no "parentheses style" options for them.
1. Separation by type (UDF vs. Built-in).
2. Global ==> Parentheses, to apply to UDFs, by our choice.
