Yes... it gets copied from a var "pathname"... I changed the name to 
inline_filename to remove this confusion in the new code anyway.  And I 
removed name here and just use walk_tree_ctx->inline_filename.

OK.  Actually this was a modified cut-n-paste from your patch's 
implementation in print_object().  So I also changed that code to follow 
this scheme.

	if (use_render) {
		if (render)
			render_buffer(render, basename, buf, size);
		else
			include_file(path, mimetype);
	} else {
		print_buffer(basename, buf, size);
	}

became

         if (!use_render)
                 print_buffer(basename, buf, size);
         else if (render)
                 render_buffer(render, basename, buf, size);
         else
                 include_file(path, mimetype);
