最近在整理书签的时候发现一个奇怪的事情，我使用自己写的包 toc-glue.el 将ToC转换成Lisp的时候发现，使用toc-glue:toc-to-lisp的时候，在调用过一次后它作用的buffer会被固定，即使我修改了当前的ToC buffer，它运行输出的结果也是不变的，重新加载toc-glue.el可以解决此问题，但是再执行一次后内容又会被固定。我一开始怀疑是惰性加载造成的，但是我删掉autoload后手动加载发现还是有这个问题。感觉这应该不是emacs的bug，但是我想不出问题出在哪儿，于是来论坛向各位高手求助。
以下是一个可以用来测试的ToC文件，如果您对此问题感兴趣，可以安装此包后进行测试：

测试步骤：
- 将上面的文件保存为
test.toc - 安装toc-glue.el ，该插件只有单个elisp文件，确保该文件所在路径存在于你的
load-path中即可。 - 打开
test.toc，(require 'toc-glue)，然后启用toc-glue-toc-mode - 按下
C-c C-c，可以看到初次运行函数后的的结果。 - 修改该ToC，比如说把第一行的
PREFACE改成PRE，再次按下C-c C-c，发现运行结果还是上一次的结果，PREFACE没有变成PRE。
