Subject: [PATCH] Babel: add results value support to Scala

* lisp/ob-scala.el (org-babel-scala-wrapper-method): Use a Scala
block enclosing the submitted code.

The string representing an well formed block was not an Scala code. I
put the string from the user into an block, surrounded by an call to
replace the default output stream.
