Agreed.

`{' could be interpreted as shorthand for for `g/.*/\', but
the global command (g) masks some errors that could cause unexpected
results.

FYI, the above example in (inefficient) ed syntax:

ed  -s o.tmp <<EOF
H
/<ADDRESS>/,/<\/ADDRESS>/g/.*/\
s#href="http://www.jidanni.org/";>Dan Jacobson#href="$home">Dan Jacobson#
wq
EOF

Okay.
