Yes, beside the potential difficulty of giving direct access to the
buffer's content, there's the fact that the time needed to make a copy
will be dwarfed by the time needed by tree-sitter to parse it, turn it
into a tree, and for us to process the returned parse tree (unless we
copy a lot more than the part that tree-sitter parses, admittedly, but
presumably we shouldn't need to copy text at which tree-sitter won't
look).
