zsxwing 12671dd5e4 [SPARK-8434][SQL]Add a "pretty" parameter to the "show" method to display long strings 
Sometimes the user may want to show the complete content of cells. Now `sql("set -v").show()` displays:

The user needs to use something like `sql("set -v").collect().foreach(r => r.toSeq.mkString("\t"))` to show the complete content.

This PR adds a `pretty` parameter to show. If `pretty` is false, `show` won't truncate strings or align cells right.
