grep and bsdgrep do not recognize the '[[:<:]]' or '[[:>:]]' bracket
expressions described in re_format(7), though sed does:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
$ printf 'foobar\nfoo bar\nbaz' | grep 'foo[[:>:]]'
grep: Invalid character class name
$ printf 'foobar\nfoo bar\nbaz' | grep '[[:<:]]bar'
grep: Invalid character class name
$ printf 'foobar\nfoo bar\nbaz' | bsdgrep 'foo[[:>:]]'
bsdgrep: Invalid character class name
$ printf 'foobar\nfoo bar\nbaz' | bsdgrep '[[:<:]]bar'
bsdgrep: Invalid character class name
$ printf 'foobar\nfoo bar\nbaz' | sed -n '/foo[[:>:]]/p'
foo bar
$ printf 'foobar\nfoo bar\nbaz' | sed -n '/[[:<:]]bar/p'
foo bar
