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.
(.,.) arguments to ! command: Process specified lines through the shell
command.
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. :-)
