+Subject: [PATCH] env,printenv: only quote when outputting to terminals
+
+To support albeit non-robust but existing use cases like:
+
+  env | grep SPARK_JAVA_OPT_ | sort -t_ -k4 -n |
+   sed 's/[^=]*=\(.*\)/\1/g' > java_opts.txt
+  readarray -t SPARK_EXECUTOR_JAVA_OPTS < java_opts.txt
+  ...
+  CMD=("${JAVA_HOME}/bin/java" "${SPARK_EXECUTOR_JAVA_OPTS[@]}" ...)
+
+* src/env.c (main): Restrict quoting to terminals.
+* src/printenv.c (main): Likewise.
+* tests/env/env.sh: Adjust accordingly.
+* tests/misc/printenv.sh: Likewise.
+* doc/coreutils.texi: Likewise.
+
+Link: https://github.com/coreutils/coreutils/issues/355
+
+Upstream-Status: Backport [https://github.com/coreutils/coreutils/commit/782a1e5bc2090212273bb731dceee2cc2a071e54.patch]
