Subject: [PATCH 7/7] Remove unnecessary Qunbound check
Date: Tue, 23 Mar 2021 23:11:57 -0400	[thread overview]
Message-ID: <bb531a5171f056aff5e1e0f773984788e1780a25.1616554376.git.sbaugh@catern.com> (raw)
In-Reply-To: <cover.1616554376.git.sbaugh@catern.com>

DEFVAR_PER_BUFFER variables (which this function deals with) cannot be
Qunbound, at least right now; they're either set to a value, or
PER_BUFFER_VALUE_P is false.

* src/buffer.c (buffer_local_variables_1): Remove Qunbound check
