Exception_Information repeats the Exception_Name if the implementation
advice is followed, so explicitly outputting the name is probably
redundant.  I think it's also good practice to write information about
exceptions to the Standard_Error file instead of the Standard_Output,
as this makes it easier for the execution environment (e.g., a shell)
to separate exception information from normal output.
