Syntax highlighting for numeric literals containing underscores

[jondo]

Problem Description

I am using the numeric literals with underscores new in Python 3.6, because I need to deal with large integers. My Spyder version does not do syntax highlighting correctly with these numbers.

What steps will reproduce the problem?

Enter the integer x = 1_000_000 in the editor. The number does not get highlighted as literal like in x = 1000000.
