[MonoDevelop] Small patch to allow separate control charater higlighting

[Jacob Ilsø Christensen]

Hi.

I was about to commit your patch and wanted to try it out first. I
found two issues:

* After applying your patch MonoDevelop suddenly shows control
characters even though I have disabled it in the preferences
* I tried to change it in Edit/Preferences/Text Editor/Markers and
Rulers but got an exception:

Exception occurred: Object reference not set to an instance of an object

System.NullReferenceException: Object reference not set to an instance
of an object

Could you look at that please?

Regards,
Jacob
