+Backport of:

+Author: Sven Joachim <svenjoac@gmx.de>
+Description: Change the --disable-root-environ configure option behavior
+ By default, the --disable-root-environ option forbids program run by
+ the superuser to load custom terminfo entries. This patch changes
+ that to only restrict programs running with elevated privileges,
+ matching the behavior of the --disable-setuid-environ option
+ introduced in the 20230423 upstream patchlevel.
+Bug-Debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1034372#29
