I think your definition of "fairly small wish-list item" differs from mine. ;-)

As you surely know, ed is mostly of historical interest. Therefore 
implementing new features is not a priority. I implemented the '+linenum' 
thing because it was easy and because all other GNU editors implement it.

Some of your proposals seem pretty specialized, and others are contradictory 
('R rewind' and 'R multi-level redo). Therefore I would like to see some 
kind of consensus among ed users in this list before thinking about 
implementing any of them.

The shell escape command (!) can't have default addresses and remain 
backwards compatible. I have this feature in my todo list, but I need to 
find the time to think about it[1]. As always, patches are welcome. :-)
