Why is this patch necessary? It doesn't fix anything, it just worsens performance by adding an additional fflush call.

I don't understand what this PR is supposed to fix. I thought we've already established that calling fputc will flush correctly upon newline (presumably it calls fflush somewhere in its C library implementation), and we already have to call fputc anyway. All this PR does is just to add yet another call to flush. Why?

[WalterBright]

Ack, looks like I got turned around with "\n" versus '\n'.

Never mind!

So, will you revert the revert? :)

[CyberShadow]

Well, it was never merged, so we're good.
