What did you do?

I wrote a func with a sig so long, I wanted to try and wrap it so as to place each param on a single line, with trailing commas.

What did you expect to see?

I expected vfmt, as per its seeing current impl, to respect the formatting.

What did you see instead?

Instead it formatted the code by placing the arguments on a single line and making the line super long.
