	Now download line is printed nicely with no garbage at the end 
of
	line. I use ioctl to get the columns of terminal.
	If stdout is redirected to another device, instead of carriage 
return,
	end of line '\n' character is used. This is feature 
request#1909659
	* src/ConsoleStatCalc.cc (calculateStat)
