From: René Scharfe Date: Sun, 09 Feb 2020 15:58:42 GMT Subject: [PATCH 4/4] parse-options: simplify parse_options_dup() Message-ID: <162fb36a-6dd1-c178-9032-d3f4213930a6@web.de> In-Reply-To: <11b82734-f61c-5e73-2d0c-22208c06d495@web.de> Simplify parse_options_dup() by making it a trivial wrapper of parse_options_concat() by making use of the facts that the latter duplicates its input as well and that appending an empty set is a no-op.
