It is more readable, but according to OpenBSD's sed(1) manpage it would
also be non-portable (https://man.openbsd.org/sed#STANDARDS).  That note
was added in 2006 (https://github.com/openbsd/src/commit/24ce9718),
though, so perhaps it needs an update.

FWIW, generate-cmdlist.sh uses such a multi-line sed script in its
function get_synopsis.
