grep -b, --byte-offset returns 0

[Jonesy]

(I'm not sure if I can post to this list via nntp/gmane...)

grep'ping for a byte offset always returns 0 for the result.
Searching "FreeBSD Bugzilla – Bug List" shows no other reports.

Ubuntu 16.04:

jonesy at nix5:~$ a='now is the time for all good men to come to the aid of the party'
jonesy at nix5:~$ echo $a | grep -b -o  good
24:good


FreeBSD 12.1 

[jonz~]a='now is the time for all good men to come to the aid of the party'
[jonz~]echo $a | grep -b -o  good
0:good

I have just now created a login at bugs.freebsd.org/bugzilla/ 
and reported this bug there, but I am unsure if I did it all 
correctly.   :-)

Can someone confirm my findings?

Thank you,
Jonesy
