From a2cd709de314a7bfa038e14fd36f1d21077b4173 Mon Sep 17 00:00:00 2001 From: Ann T Ropea Date: Sun, 3 Dec 2017 22:27:39 +0100 Subject: print_sha1_ellipsis: introduce helper Introduce a helper print_sha1_ellipsis() that pays attention to the GIT_PRINT_SHA1_ELLIPSIS environment variable, and prepare the tests to unconditionally set it for the test pieces that will be broken once the code stops showing the extra dots by default. The removal of these dots is merely a plan at this step and has not happened yet but soon will. Document GIT_PRINT_SHA1_ELLIPSIS.
