What does long-line-optimizations-p produce in Magit buffers? If it
returns nil, what you see there has nothing to do with locked
narrowing, which is only used when buffer text has very long lines.
(Magit hides buffer text almost completely, presenting you what is
largely overlays and 'display' properties, so you may not be aware of
what the actual buffer text looks like.)
