I could not think using disp(). According to its expected behavior, it 
always appends an \n, while we want to stay on the line, what's the 
purpose of \r instead of \n, and mprintf() does not append anything to 
what it is requested to display.

I do not think that disp() is broken. It looks OK, while clc(1) is 
bugged <http://bugzilla.scilab.org/show_bug.cgi?id=16143>. This is why 
extra \n are required for this workaround using clc.

Now that you know the clc code, please do not hesitate to propose a 
patch for its clc(1) bug ;-))
