+From 5f712621829ed81a758077431226a86df37fbc3b Mon Sep 17 00:00:00 2001

+Subject: [PATCH] gzip: port zdiff, zless to Busybox
+
+Problem reported by Denys Zagorui (Bug#26088).
+* tests/zdiff: Check that diff uses POSIX-format output.
+* zless.in (less_version): Don't exit merely because 'less -V'
+fails; instead, assume 'less' is compatible with an old version of
+the original 'less'.  Busybox 'less -V' fails, but apparently its
+'less' works anyway somehow.
+
+Signed-off-by: Denys Zagorui <denys.zagorui@globallogic.com>
+
+Upstream-Status: Accepted
