Description

Currently "hadoop fs -help count" fails to show help about only count command.
Instead it displays following output

[rphulari@statepick-lm]> bin/hadoop fs -help count
hadoop fs is the command to execute fs commands. The full syntax is: 

hadoop fs [-fs <local | file system URI>] [-conf <configuration file>]
	[-D <property=value>] [-ls <path>] [-lsr <path>] [-df [<path>]] [-du <path>]
	[-dus <path>] [-mv <src> <dst>] [-cp <src> <dst>] [-rm [-skipTrash] <src>]
	[-rmr [-skipTrash] <src>] [-put <localsrc> ... <dst>] [-copyFromLocal <localsrc> ... <dst>]
	[-moveFromLocal <localsrc> ... <dst>] [-get [-ignoreCrc] [-crc] <src> <localdst>
	[-getmerge <src> <localdst> [addnl]] [-cat <src>]
	[-copyToLocal [-ignoreCrc] [-crc] <src> <localdst>] [-moveToLocal <src> <localdst>]
	[-mkdir <path>] [-report] [-setrep [-R] [-w] <rep> <path/file>]
	[-touchz <path>] [-test -[ezd] <path>] [-stat [format] <path>]
	[-tail [-f] <path>] [-text <path>]

Expected output of "bin/hadoop fs -help count " should be

[rphulari@statepick-lm]> bin/hadoop  fs -help count
-count[-q] <path>: Count the number of directories, files and bytes under the paths
		that match the specified file pattern.  The output columns are:
		DIR_COUNT FILE_COUNT CONTENT_SIZE FILE_NAME or
		QUOTA REMAINING_QUATA SPACE_QUOTA REMAINING_SPACE_QUOTA 
		      DIR_COUNT FILE_COUNT CONTENT_SIZE FILE_NAME
