Improve "Hide whitespaces changes": do not highlight trailing comma #2382

Hello, It happens really often that I'm adding one parameter to a lot of functions. The diff on Github now looks like this:

fun myFunction(
-   oldParameter: Int
+   oldParameter: Int,
+  newParameter: Int
) {

}

fun otherFunction(
-   oldParameter: Int
+   oldParameter: Int,
+  newParameter: Int
) {

}

Two thirds of this diff is noise, I'm not modifying oldParameter in any way, other than adding a comma exactly at the end of the line in order to add a new parameter. There is no chance to forget adding this comma because the compiler would complain immediatly.

So what I would really like Github to be smarter about that exact use case.

Specifically, If I choose the option Hide whitespace changes

Then I would love to see this:

fun myFunction(
   oldParameter: Int,
+  newParameter: Int
) {

}

fun otherFunction(
   oldParameter: Int,
+  newParameter: Int
) {

}
