bsdgrep: does anyone see this?

Hi,

On the latest -CURRENT of r227785, I found bsdgrep acts differently
from GNU grep; bsdgrep -R exits at first unreadable directory.

==
$ bsdgrep -R ddb /etc/
/etc/defaults/rc.conf:ddb_enable="NO"           # Set to YES to load ddb scripts at boot.
/etc/defaults/rc.conf:ddb_config="/etc/ddb.conf"        # ddb(8) config file.
grep: /etc/bluetooth/hcsecd.conf: Permission denied
grep: /etc/ntp: Permission denied

$ gnugrep -R ddb /etc/
/etc/defaults/rc.conf:ddb_enable="NO"           # Set to YES to load ddb scripts at boot.
/etc/defaults/rc.conf:ddb_config="/etc/ddb.conf"        # ddb(8) config file.
