Comment:
Actually the bug exists still in HEAD (7.0). I ran across it and took the
time to fix it, closing a long standing TODO in InteractiveEval.hs
I am attaching the fix for merging to HEAD. The patch is lightweight
enough to include it in 7.01 imho. Instead of looking around to find the
enclosing declaration of a tick, this patch makes use of the information
already collected during the coverage desugaring phase.
