[PATCH 18/29] config: fix leaking "core.notesref" variable

From
Patrick Steinhardt <ps@pks.im>
Date
Jun 3, 2024, 09:47 UTC
Message-ID
<cff6303ce1ce8e921adfae3eada216eca71b2c29.1717402439.git.ps@pks.im>
In-Reply-To
<cover.1717402439.git.ps@pks.im>

The variable used to track the "core.notesref" config is not getting freed before we assign to it and thus leaks. Fix this.
