Subject: [PATCH] Fix arbitrary command execution in ed-style patches
(CVE-2018-1000156)
* 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.

Subject: Don't follow symlinks unless --follow-symlinks is given
* src/inp.c (plan_a, plan_b), src/util.c (copy_to_fd, copy_file,
append_to_file): Unless the --follow-symlinks option is given, open files with
the O_NOFOLLOW flag to avoid following symlinks. So far, we were only doing
that consistently for input files.
* src/util.c (create_backup): When creating empty backup files, (re)create them
with O_CREAT | O_EXCL to avoid following symlinks in that case as well.
