From 2320ac3349789551e9c7500dba03e04b9ac02f41 Mon Sep 17 00:00:00 2001
From: David Gibson <david@gibson.dropbear.id.au>
Date: Fri, 10 Jun 2022 12:32:42 +1000
Subject: Don't abbreviate ip(8) arguments in examples and tests

ip(8)'s ability to take abbreviated arguments (e.g. "li sh" instead of
"link show") is very handy when using it interactively, but it doesn't make
for very readable scripts and examples when shown that way.
