patch: fix CVE-2018-
1000156
* CVE detail: https://nvd.nist.gov/vuln/detail/CVE-2018-
1000156
* upstream tracking: https://savannah.gnu.org/bugs/index.php?53566
* Fix arbitrary command execution in ed-style patches:
- 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.
