Thanks for the proposal. There have been various suggestions over the years
about additional information attached to each history entry, including
$PWD, $?, etc., but there are issues with doing that. Where $? starts to 
get messy, for example, is with asynchronous commands -- how do you tie the
exit status of an arbitrary background job back to the right history entry?
