From 732b0825475c1a2466a6abf6e223b2a77af011f2 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Mon, 6 Mar 2023 14:27:21 +0100 Subject: [PATCH] nvedit: simplify do_env_indirect() Instead of calling env_get(from) up to three times, just do it once, computing the value we will put into 'to' and error out if that is NULL (i.e. no 'from' variable and no default provided). No functional change.
