That qed was done in the 1970s by Tom Duff, Hugh Redelmeier, David
Tilbrook and myself. The regular expressions are from ed, plus simple
forms of parentheses, alternation, and backreferences and a couple of
minor tweaks that later appeared in vi.
It's essentially ed with some original qed features put back in, but
with our spin. These include multiple files (buffers), string
registers, and a couple of related commands.
