Subject: [PATCH v4 5/7] commit-graph: early exit to "usage" on !argc
Date: Mon, 23 Aug 2021 14:30:19 +0200	[thread overview]
Message-ID: <patch-v4-5.7-2983e16ba69-20210823T122854Z-avarab@gmail.com> (raw)
In-Reply-To: <cover-v4-0.7-00000000000-20210823T122854Z-avarab@gmail.com>

Rather than guarding all of the !argc with an additional "if" arm
let's do an early goto to "usage". This also makes it clear that
"save_commit_buffer" is not needed in this case.
