add varakappa to to tex--prettify-symbol-list

[Uwe Brauer]

Hi 

I would like to add varrkappa to the tex--prettify-symbol-list

Some years ago, Tassilo provided me a function, I attach. 

I just added 
              ("\\varkappa" . ?\u03F0)

to his function and it works nicely.
But suggest to have it also included in the official repository. I
searched the repository but cannot find anything.
Any idea what to do?

Thanks
