Subject: [PATCH 6/7] help: add --no-[external-commands|aliases] for use with --all
Date: Tue, 28 Dec 2021 16:35:11 +0100 [thread overview]
Message-ID: <patch-6.7-a5ef9f69530-20211228T153456Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-0.7-00000000000-20211228T153456Z-avarab@gmail.com>
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.
