incomplete help message is displayed for getmerge [addnl] option
----------------------------------------------------------------

                 Key: HADOOP-7340
                 URL: https://issues.apache.org/jira/browse/HADOOP-7340
             Project: Hadoop Common
          Issue Type: Improvement
          Components: fs
    Affects Versions: 0.23.0
            Reporter: XieXianshan
            Assignee: XieXianshan
             Fix For: 0.23.0


The help message for the command "hdfs dfs -help getmerge" is displayed like this:
"-getmerge <src> <localdst> [addnl]:	Get all the files in the directories that
		match the source file pattern and merge and sort them to only
		one file on local fs. <src> is kept."
and the information about [addnl] option is missed,despite the fact that [addnl] option is
implemented.

Therefore,the expected message should be displayed like this:
"-getmerge <src> <localdst> [addnl]:	Get all the files in the directories that
		match the source file pattern and merge and sort them to only
		one file on local fs. <src> is kept.
		  addnl   Optionally addnl can be set to enable adding a newline 
		          character at the end of each file."
