Summary: GHCi: missing .hs gives unhelpful msg

Initial Comment:
Trying to load a module (via an import chain) for
which the .hs does not exist results in the
following message:

   *** Exception: does not exist
  Action: withFileStatus
  Reason: No such file or directory
  Prelude> 

It took me a while to figure out what was going on.
It would have helped tremendously to know what
file was missing.

It might be best to treat a missing .hs as an
infinitely old .hs (perhaps with an indication that
it is missing.)

(The missing .hs resulted from the writing the
make rules for creating a library including GreenCard
code in the straightforward way.)
