Description

Hi,

I wanted to draw attention to the fact that formatted-raw string literals are syntax highlighted by MagicPython as if they were ordinary raw string literals, without any special syntax highlighting given to the contents of the curly braces. See examples below:

![frstrings](https://user-images.githubusercontent.com/37582022/44036651-2e88da12-9f0a-11e8-829f-5ff8621bbde0.PNG)

Is there any chance this could fixed/enhanced?

Cheers!

Research direction

Start by locating the syntax-highlighting rules for formatted-raw string literals and compare their handling with ordinary raw strings. Use the reported `fr"{some_path_here}\\some_file_here.txt"` example to verify that the contents inside curly braces receive distinct highlighting.
