Description Michael Tokarev 2012-12-18 08:27:17 UTC 
Originally reported in Debian, http://bugs.debian.org/695862 against busybox 1.20:

$ echo foop | grep -w foo
$ echo foop | busybox grep -w foo
$ echo foop | fgrep -w foo
$ echo foop | busybox fgrep -w foo
foop

So, busybox grep handles -w correctly, while busybox Fgrep does not.
