I noticed that, when a highlighted C# snippet ends with a comment, that comment is not recognised. This is caused by the lexer requiring a end of line (\n) after a comment.

While that works fine for regular program code, when we highlight code snippets that are part of a bigger program, a comment at the end often helps to put thing into perspective. (And so should be recognised.)

This pull request does:

• Add comment highlight in the C# lexer for when the code ends with a comment.
• Update the C# test data with a comment in the end.
• Update the expected test data.

Let me know if something can be done better or prefer a different way.

Thanks for your consideration. 🙂
