-Subject: [PATCH 06/17] Fix arbitrary command execution in ed-style patches
- (CVE-2018-1000156)
+Date: Wed, 7 Feb 2018 12:10:41 +0100
+Subject: [PATCH 02/17] Test suite compatibility fixes
-* src/pch.c (do_ed_script): Write ed script to a temporary file instead
-of piping it to ed: this will cause ed to abort on invalid commands
-instead of rejecting them and carrying on.
-* tests/ed-style: New test case.
-* tests/Makefile.am (TESTS): Add test case.
+* 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.
