Trailing commas disallow short lines from being collapsed

val foo =
    Short(
        "one",
        "two",
    )

will not be reformatted, but

val foo =
    Short(
        "one",
        "two"
    )

will be reformatted to

val foo = Short("one", "two")

There is no reason I can think of to ever do that, so the formatter makes an opinion that this is not allowed. For that same reason I’m advocating that the formatter also make an opinion about trailing commas and collapsing short lines.

It shouldn’t do that TBH, because literally the intention of setting ; there, is to have the code in one line, there is no other reason to put ; there if it is not getting a single line…
