Question regarding readf

[Andre Pany]

Hi,

following the example from http://ddili.org/ders/d.en/input.html,
I try to read a value from console on windows (powershell and dos 
console).

The code from the example does not work,
writeln is never executed.

import std;

void main()
{
	while(true)
	{
		string name;
		readf("%s", name);
		writeln(name);
         }
}

also this doesn't work:
readf(" %s", name);

It only works while changing the line to:
readf("%s\n", name);

I wonder why the example from Ali is invalid. Did the behavior 
changed in the past?

Kind regards
André
