 Replying to [comment:1 nilason]:

 port).

 Yes, sorry, I was looking at the version in
 [fb098cb6c9a5df0e16d138b692fdf81abdf61e27/macports-ports].

 reason to this.

 I guess the ability to use `\n` to mean a newline in the replacement
 pattern is not something that was present in the version of `sed` that
 shipped before macOS 11:

 {{{
 % sw_vers -productVersion
 10.15.7
 % echo hello | sed 's|hello|&\nworld|'
 hellonworld
 %
 }}}

 A workaround is to literally insert a newline in the replacement string,
 rather than an `n`:

 {{{
 % echo hello | sed 's|hello|&\
 world|'
 hello
 world
 %
 }}}
