You need to read it more carefully. There are two kinds of regular
expressions, "basic" and "extended". sed, ed, and grep speak BRE
syntax, whereas awk and egrep speak ERE syntax. + is special only in
ERE syntax.
(And then there's GNU, where the difference between BRE and ERE is that
some things use a preceding backslash in BRE and don't in ERE, and vice
versa, so GNU sed does what you want if you use \+ instead of +.)
