Scalariform does not understand trailing comma

[marekzebrowski]

reproducer

case class A(
a: Int,
b:Int,
)

[exp0nge]

Is this ever going to be addressed?

[charpov]

It's a small thing, but so annoying.

[exp0nge]

@charpov use scalafmt instead

@exp0nge scalafmt also has trouble with some trailing commas, though it's ok with most of them.

[charpov]

I tried scalafmt once and didn't like it. I don't remember why now. I'll give it another shot.

This is an issue with scalariform, not with sbt-scalariform. I made a pull request in scalariform that takes care of this problem: scala-ide/scalariform#296. Let's see if it gets merged and makes into a new release, then we could bump the scalariform version here in sbt-scalariform to make the fix available for this plugin.
