Humm, thank you for the feedback.
But this is one of the difficult ones with the current parse implementation...
Let me think.

Built-in syntax highlighter for markdown allow many wired things I've never use, say allow double ` for inline code.

I don't know where does these come from, and just defining a simpler highlight rule set for my own use. For example, don't allow any newline for inline code blocks, more strict rules for simple Regex.

Anyway, robust highlight is just an impossible task for Regex, even for languages with such a seemingly straightforward syntax.
