NetBSD iceland 6.1_STABLE NetBSD 6.1_STABLE (SDF6.amd64) #0: Tue Nov 26 12:49:14 UTC 2013  root@bjork:/spare/netbsd/src/sys/arch/amd64/compile/SDF6.amd64 amd64
>Description:
When using the grep command with both the -i and -o options, no matches
are returned unless the case matches, meaning that the -i option is
being ignored.
>How-To-Repeat:
unicorn@iceland:~% echo OMICRON | grep -oi micro
unicorn@iceland:~% echo omicron | grep -oi micro
micro
unicorn@iceland:~%
>Fix:
It seems that the version of GNU grep included is about 13 years old:

| unicorn@iceland:~% grep -V
| grep (GNU grep) 2.5.1 nb1

This may be partly because the GNU web site is woefully out-of-date,
claiming that version 2.5.1a is the latest stable release, when numerous
versions have come out since then, and every other O/S seems to have a
version much newer than that.  Please update to a newer version in NetBSD
as well.

 I noticed this PR after having stumbled over several problems of my
 own with the aged version of grep that's installed. (One could of
 course install GNU grep 2.19 from pkgsrc and use that instead.)

 This example works correctly with new versions of GNU grep and also
 the BSD licensed version that's found in src/usr.bin/grep which
 hasn't supplanted GNU grep yet.
