[feature request] clicking on matlab .m files should open them with syntax highlighting

As titled; notebook info:

About Jupyter Notebook
Server Information:

You are using Jupyter notebook.

The version of the notebook server is 5.0.0 and is running on:

Python 3.6.2 |Anaconda, Inc.| (default, Sep 22 2017, 02:03:08) 
[GCC 7.2.0]

Current Kernel Information:

Matlab Kernel

• What I do: I launch jupyter notebook, open my browser, and clicks no the title of a matlab .m file.

• What happens: a new tab pops up with the contents of that file in plaintext.

• What I want to happen: a new tab pops up with the contents of that file with syntax highlighting, and maybe with editing.

• What is currently achievable: I can click the checkbox in front of that file, and select edit. Then pull down the dropbox to get Octave syntax highlighting, which is basically the same thing

• Suggestion: make editing & octave syntax highlighting the default behavior when clicking on a .mat file's title

Notes:

1. Now, I understand that us matlab people are usually too stupid, busy, or lazy to use Jupyter notebook, but from the standpoint of an ignorant user like me, implementing this should be relatively simple. Unless, of course, it is not. I hope there aren't any deep technical issues or legal issues preventing us from doing this?
2. If you are on the jupyter notebook project or are looking at this issue because you want to contribute, you are an awesome human being and deserve to be proud of yourself.

Just wanted to follow this up. Is there a convenient way to change default syntax highlighting based on file extension in the text editor? I'm not particularly concerned with default behavior, I'd just like to be able to set {".m": "octave"} somewhere in the text editor options.
