Syntax highlighting (based on CodeMirror) is a beta feature on all
left-to-right wikis:

(It'll come to right-to-left wikis as soon as the RTL problems have been fixed.)
There's not going to a big MassMessage to all the wikis about this,
but if you think it'll be helpful, please spread the word in your
community, on your local Village Pump etc.
