From 949e123d7a81fee972d87fa6591bb63fe3fb920d Mon Sep 17 00:00:00 2001 From: Karsten Blees Date: Mon, 6 Apr 2015 21:37:18 +0200 Subject: [PATCH] mingw: initialize HOME on startup HOME initialization was historically duplicated in many different places, including /etc/profile, launch scripts such as git-bash.vbs and gitk.cmd, and (although slightly broken) in the git-wrapper. Even unrelated projects such as GitExtensions and TortoiseGit need to implement the same logic to be able to call git directly. Initialize HOME in git's own startup code so that we can eventually retire all the duplicate initialization code.
