From 3fc4998f31ffc7dfccfc4a3dde36184475c796ca Mon Sep 17 00:00:00 2001
From: Andreas Gruenbacher <agruen@gnu.org>

Subject: [PATCH] Test suite compatibility fixes

* tests/crlf-handling, tests/git-cleanup, tests/test-lib.sh: Use printf
instead of echo -e / echo -n for compatibility with systems that don't
support these echo options.
* tests/merge: Minor other cleanups.
