From: Karsten Blees <blees@xxxxxxx>
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.
