/usr/src/usr.bin/grep/grep: is the FreeBSD grep (only built if MKBSDGREP=yes)
/usr/bin/grep: is actually the GNU grep (bec. MKBSDGREP=no; see mk.conf(5))

/usr/bin/grep is the GNU grep
/rescue/grep is the FreeBSD grep

Good question. Probably incompatibilities and/or bugs. Other people
have reported both. I've noticed a few myself.
