From 1ce590133b545aa735683f46003d12df624d67af Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Mon, 21 Feb 2022 20:38:51 +0100 Subject: [PATCH] help: add --no-[external-commands|aliases] for use with --all MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add the ability to only emit git's own usage information under --all. This also allows us to extend the "test_section_spacing" tests added in a preceding commit to test "git help --all" output. Previously we could not do that, as the tests might find a git-* command in the "$PATH", which would make the output differ from one setup to another.
