dfs -getmerge  should process its argments better 
--------------------------------------------------

                 Key: HADOOP-1004
                 URL: https://issues.apache.org/jira/browse/HADOOP-1004
             Project: Hadoop
          Issue Type: Bug
            Reporter: arkady borkovsky


The command only works if its argument is a directory
If the argement is a file or a wildcard, it does nothing without any message.
If not arguments are given, the command fails with a stack dump.

The improved version should:
-- produce an error message in case it cannot perform meaningful action (no argument, or no
matching files)
-- copy the files specified by a wildcard expresstion.  (A single file is special case of
this).
