if linewrapping is just a rendering option in the editor, why not let
the user decide if he likes it or not? If no permanent changes were made
to the m-file itself, there should be no harm done. Enabling
line-wrapping in any old editor usually does not change the file as such...
The non-existent linewrapping for "Code" cells makes editing complex
long cells quite painful and seems for my taste something that would
people put off using the otherwise very nice new package editing
features in the frontend.
As for workbench, surely there is an option there to enable
line-wrapping (dunno, though)?
