From b2f55717c7f9b335b7ac2e3358b0498116b94a5d Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Wed, 1 Nov 2017 18:10:33 +0100 Subject: [PATCH] mingw: document the standard handle redirection This feature has been in Git for Windows since v2.11.0(2), as an experimental option. Now it is considered mature, and it is high time to document it properly.
