RemoveUnusedImports: trailing whitespace

[cvogt]

-import scalaz.concurrent.{ Future, Task }
+import scalaz.concurrent.Task

Task is followed by a space.

Thanks for reporting! This should be fixable, but note that RemoveUnusedImports does a best-effort only to preserve formatting. It's recommended to run formatter after the rewrite.

I've also noticed this

-import scala.util.control.{ NonFatal, Breaks }
+import scala.util.control. NonFatal 

which is more annoying than the trailing whitespace.

A very ad-hoc (but probably reasonable) solution would be to remove all surrounding whitespaces when removing the curly braces.

I've been meaning to simplify the remove importee implementation. It shouldn't have to be this complicated.

The bug did not surface in the tests since they used import a.{b,c} instead of import a.{ b, c }.
