Comment (by jamrial):

 Newer sed shows

 $ sed --help
 Usage: sed [OPTION]... {script-only-if-no-other-script} [input-file]...

   -n, --quiet, --silent
                  suppress automatic printing of pattern space
   -e script, --expression=script
                  add the script to the commands to be executed
   -f script-file, --file=script-file
                  add the contents of script-file to the commands to be
                  follow symlinks when processing in place
   -i[SUFFIX], --in-place[=SUFFIX]
                  edit files in place (makes backup if SUFFIX supplied)
   -b, --binary
                  open files in binary mode (CR+LFs are not processed
   -l N, --line-length=N
                  specify the desired line-wrap length for the `l' command
                  disable all GNU extensions.
   -E, -r, --regexp-extended
                  use extended regular expressions in the script
                  (for portability use POSIX -E).
   -s, --separate
                  consider files as separate rather than as a single,
                  continuous long stream.
                  operate in sandbox mode (disable e/r/w commands).
   -u, --unbuffered
                  load minimal amounts of data from the input files and
                  the output buffers more often
   -z, --null-data
                  separate lines by NUL characters
       --help     display this help and exit
       --version  output version information and exit

 So looks like it should be a matter of replacing that -E with -r, assuming
 it doesn't break any other target.
