> This PR is to address a few existing issues in Explain:
> - The `Explain` options `LOGICAL | FORMATTED | EXTENDED | CODEGEN` should not
> be 0 or more match. It should 0 or one match.
> - The option `LOGICAL` is not supported
> - The output of `Explain` contains a weird empty line when the output of
> analyzed plan is empty. For example:
> {noformat}
> == Parsed Logical Plan ==
> CreateTable
> CatalogTable(`t`,CatalogTableType(MANAGED),CatalogStorageFormat(None,Some(org.apache.hadoop.mapred.TextInputFormat),Some(org.apache.hadoop.hive.ql.io.
>
> HiveIgnoreKeyTextOutputFormat),None,false,Map()),List(CatalogColumn(col,int,true,None)),List(),List(),List(),-1,,1462725171656,-1,Map(),None,None,None),
> false
>
> == Analyzed Logical Plan ==

> CreateTable
