Hi Alan,

Thanks for creating markdown-toc, I enjoy using it.

I recently discovered a really bizarre edge case bug that you might be interested in.

Summary

If you have a heading line which is directly followed by a <code-snippet-with-angle-brackets> and the code snippet has the same text as the heading, the TOC generated by TOC: insert/update gets cut off.

Below is an example. See how the generated TOC doesn't go further than Heading3...

------- BEGIN EXAMPLE ----------

<!-- TOC -->

- [Heading1](#heading1)
- [Heading2](#heading2)
- [Heading3](#heading3)

<!-- /TOC -->

## Heading1 ##

Some text

## Heading2 #

Some more text, with a ```<heading2>``` code snippet

## Heading3 ###

```<heading3>``` code snippet is the first entry after the heading, and has the same name

Suspect that this code snippet is the culprit

## Other Heading ##

Expect to see this other heading in the TOC

## Also Expected ##

Will this turn up in TOC?
