I agree with both proposals.  :-)

The output of =E2=80=98herd status=E2=80=99 is meant for humans to read, no=
t for
machines to process, so it makes sense to make these changes IMO.  For
machines there=E2=80=99s a well-defined protocol that can be used, so we sh=
ould
do our best to make =E2=80=98herd status=E2=80=99 useful to humans.

If you want to give it a try, this is all happening in
modules/shepherd/scripts/herd.scm.

Thank you,
Ludo=E2=80=99.
