Added more scenarios where comma to be removed in the function arg This is an attempt to address the problem methion in https://github.com/rust-lang/rust/issues/106304#issuecomment-1837273666. Copy the annotation to explain the fix If the next Error::Extra ("next") doesn't next to current ("current") ``` fn foo(_: (), _: u32) {} - foo("current", (), 1u32, "next") + foo((), 1u32) ``` If the previous error is not a `Error::Extra`, then do not trim the next comma ``` - foo((), "current", 42u32, "next") + foo((), 42u32) ``` Frankly, this is a fix from a test case and may not cover all scenarios
