The actual status for good conditions of tests in Windows are:
Sources from autocrlf *.out ending sed stuff
git true CRLF no
git input LF yes
git false LF yes
archive N/A LF yes
We need to have the sed stuff for sources archives.
Thus we need that the endings of tests/*.out files be always LF only.
We don't want to depend on user config.
Thus this changes.
Advantage: This config is under version control, it applies to all users.
Get rid of legacy config 'core.autocrlf=true'
