Github Gists syntax highlight is not working

gist, github

Solution

Here's the solution:

You need to place a proper file extension for the filename you are trying to save, for example

Python RegEx

should become

Python RegEx.md

Spaces are ignored.

Problem

I am trying to create a gist with Markdown syntax highlight. Unfortunately can't post a screenshot here. Then I press 'save' and get no syntax highlight applied. The same issue is there with Python code.
