Fix the remaining tests that failed with core.autocrlf=true

The test suite is mainly developed on Linux and MacOSX, which is the reason that nobody thought to mark files as LF-only as needed. The symptom is a test suite that fails left and right when being checked out using Git for Windows (which defaults to core.autocrlf=true). Mostly, the problems stem from Git's (LF-only) output being compared to hard-coded files that are checked out with line endings according to core.autocrlf (which is of course incorrect). This includes the two test files in t/diff-lib/, README and COPYING. This patch can be validated even on Linux by using this cadence: git config core.autocrlf true rm .git/index && git stash make -j15 DEVELOPER=1 test Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Reviewed-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
