From 67fe7356538c714da9da6061abe99209452260d7 Mon Sep 17 00:00:00 2001 From: Erik Faye-Lund Date: Tue, 4 Dec 2012 09:10:40 +0100 Subject: [PATCH] compat/terminal: separate input and output handles On Windows, the terminal cannot be opened in read-write mode, so we need distinct pairs for reading and writing. Since this works fine on other platforms as well, always open them in pairs.
