LaTeX syntax highlighting in Rmd

• VSCode Version: 1.28.0
• VSCode-R Version: v0.6.2
• OS Version: x86_64-apple-darwin15.6.0 (64-bit)

Steps to Reproduce:

1. Use two reserved markdown characters in LaTeX math blocks in the same line
2. Syntax highlighting does not consider the LaTeX math notation and applies styling

Example of issue (with totally made up math)

Expected something more like this

TBH, simply catching the use of LaTeX and removing the syntax highlighting between paired $..$ or $$..$$ would be a great improvement.

Example text

For each $x_i$, consider all $x_i < k$.
Is $x*2$ greater than $y*2$?

$$
y_i = m * x_i + b
$$

We use embedded languages to provide syntax highlighting for code blocks of Python, C etc. in Rmd files. It should be possible to do this for LaTeX too. The difference is that grammars for Python, C etc. are built in to VS Code itself, but LaTeX isn’t built in. (The built-in languages are here: microsoft/vscode@master/extensions)

FYI, LaTeX is now built in code-insiders.

Once PR #228 is merged, I’ll fix this so that text in $..$ and $$..$$ is highlighted as LaTeX (if the user has installed an extension that provides LaTeX highlighting), or has no highlighting (if they haven’t installed such an extension).
