在给定以下noweave -html -index -n hello.nw > hello.htm文件的情况下运行hello.nw时，我的noweb html输出中的每个文档部分（甚至在html doctype之前之前）都出现星号：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "http://www.w3.org/TR/html4/frameset.dtd">
<html>
<head>
<title>Hello noweb</title>

<body>
<h1>Noweb test</h1>
<p>A noweb hello world.
<<main.c>>=

<<Main function>>

<h2>The main function</h2>
<p>Blablabla...</p>
<<Main function>>=
int main() {
printf("Hello %s!\n", NAME);
return MEANING_OF_LIFE;
}

<p>Blablabla...</p>

这是输出（请注意在doctype之前出现星号！？）：

这仅在打开索引功能时发生，也仅在我使用html标记启动doc部分时发生。在此处的wc示例（https://www.cs.tufts.edu/~nr/noweb/examples/wc.nw.html）上运行相同命令时，似乎根本不会发生这种情况，但我无法弄清楚自己在做什么错。
