I have installed a new error handler which allows recursive errors
and errors in the error handler to be handled by the error handler.
There is a separate error handler stack group for each error
being looked at.

Also, errors in nonselected processes should work better now.
The erring process will be selected while you are in the error handler.
When you exit, it will come back.
To reselect the top window, just typing CALL should be enough.
This will no longer leave the error handler in a wedges state.
The process you which had the error will still be running the error
handler until it is reset.

It now works to throw through an error handler foothold.

Additional reliability should come from the fact that the printing of the
error message is done inside an ERRSET (!).

More improvements will be coming soon.
