These variables were added in 16805d3e (t/t91XX-svn: start removing use of "git-" from these tests, 2008-09-08) so that running: git grep git- would return fewer hits. At the time, we were transitioning away from the use of the "dashed" git-foo form. That transition has been over for years, and grepping for "git-" in the test suite yields thousands of hits anyway (all presumably false positives). With their original purpose gone, these variables serve only to obfuscate the tests. Let's get rid of them. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
