Subject: [PATCH 03/12] builtin/show-ref: fix leaking string buffer
Date: Tue, 24 Oct 2023 15:10:48 +0200	[thread overview]
Message-ID: <ae2e401fbd86500381ca9e579d40ebc4fd683f89.1698152926.git.ps@pks.im> (raw)
In-Reply-To: <cover.1698152926.git.ps@pks.im>

[-- Attachment #1: Type: text/plain, Size: 1014 bytes --]

Fix a leaking string buffer in `git show-ref --exclude-existing`. While
the buffer is technically not leaking because its variable is declared
as static, there is no inherent reason why it should be.
