/usr/bin/grep *is* GNU grep in FreeBSD:

% keramida at kobe:/home/keramida$ grep --version
% grep (GNU grep) 2.5.1-FreeBSD

AFAIK, Gabor Kovesdan is working on replacing grep(1) with a
BSD-licensed implementation, but he also tries to keep UI
compatibility as much as possible.  So I guess the -r/-R option
should work in that version too once it hits the tree.
