-r here is for the 'I' (same as 'i') modifier, which means case
insensitive.  non-GNU sed might not have the '-r' option or the 'I'
('i') modifier.

I dunno about the strict rules of 'Signed-off-by' things but what i have
seen are all _exactly_ of this form.  I have never seen something like
'SIGNED-OFF-BY' or 'sIGneD-oFf-bY'.

If only the exact case sensitive form is allowed, then we can safely
remove the '-r' and 'I'.

Also, to Mark, as a quick alternative to work around these sed issues,
you can install the gsed port.  IIRC, opendarwin has this port.

Speaking of other portability issues, i made up a patch to make cogito
properly work under fbsd (without hurting others hopefully) weeks ago:

1) expr would regard a negative $dtz as an option (-xx).
2) coloring for both terminfo & termcap terminal.
