Windows Msys terminal not flushing on newlines

[Anonymouse via Digitalmars-d-learn]

I installed Git for Windows which comes with the Msys terminal, 
and I noticed writeln lines aren't being flushed on linebreaks. I 
had this a long time ago and thought I fixed it with the 
following, but I guess I never confirmed that it actually worked. 
I'm not sure where I copied it from, a TWiD perhaps?

```d
import std.stdio : stdout;
import core.stdc.stdio : _IOLBF;
stdout.setvbuf(4096, _IOLBF);  // arbitrary number
```
Is this not the right way to go about things? At least for Msys 
it seemingly does nothing.
