Syntax highlight is broken if any word start with _ inside an html tag

[gfpacheco]

The syntax highlighter must be thinking that the _ means it's gonna be italic:

# GitHub Markdown

<a href="#">A working html tag</a>
<a href="#" target="_blank">From here on the syntax highlight is broken</a>

PS: I just realized that the GitHub syntax highlighter also renders it wrong in this case. I'm also telling them that.

This also occurs with pre-formatted text sections.

As an example, the following pre-formatted section breaks highlighting:

Folder/
    _specialFolder/
    AnotherFolder/

In Atom with the Github-flavoured Markdown language specified, this text will be highlighted as though formatted with italics; the preview (which I understand is handled in a different package) formats everything correctly.

Backslash escapes do not resolve the issue; the formatting is correct, but the preview displays the escaping backslash.

PS: In my case, it seems the GitHub syntax highlighter is not also broken (or else they fixed it!).
