SafeHaskell: Restore comment although we don't know what it means.

Comment was removed as I thought it was incorrect now with code
changes but Simon M thinks my interpretation of the comment
was incorrect. He isn't sure what the comment is refereeing to
either though! So have restored comment and created trac #5249
to track fixing this at some point.
