 by coincidence I've just noticed that the Latex package 'listings' has

 This is great. However, it says there (c) 2013, so I'm wondering 
 whether this could use some update? 
OK, sorry to populate this thread all by myself, but here is some news. 
I'm attaching a small example Latex document with some incorporated 
updates. The long lists in the "morekeywords" fields are essentially the 
updates to hansl since 2013. Of course, eventually we should get those 
right into the listings package.
The document compiles fine for me with pdflatex.
The syntax coloring style right now is pretty arbitrary, see the colors 
I chose in the \lstset block.
 Ignacio, if you read this, do you have any hints on how to get changes 
 into the listings package? 
This question still applies.
thanks,
sven
