From 01d3a526ad9a37938f3597b2c160d699904cb8b8 Mon Sep 17 00:00:00 2001 From: Michael Haggerty Date: Thu, 26 Oct 2017 10:18:53 +0200 Subject: [PATCH 1/1] t0000: check whether the shell supports the "local" keyword Add a test balloon to see if we get complaints from anybody who is using a shell that doesn't support the "local" keyword. If so, this test can be reverted. If not, we might want to consider using "local" in shell code throughout the git code base.
