Thank you for sharing this patch (and the revised version).

If I understand the situation correctly, ed is mostly of historical 
interest. Therefore my two priorities are keeping it bug-free and minimizing 
the maintenance effort. I'm afraid this patch goes against these two goals.

If there were a consensus among ed users that this feature is useful, I 
would happily look into this, but I have not yet seen enough demand for such 
a radical change.

Best regards,
Antonio.
