Details:

Hi,

Using -i with -o produces unexpected results.

testfile contains:
Bonjour le monde.
Hello world.
Bonjour le monde.

But the command:
grep -o -i HELLO testfile
produces no output.

If I specify the pattern in all lowercase (grep -o -i hello testfile), I get
the expected result:
Hello

I would expect it to work the same regardless of the case of the pattern,
since -i means ignore case.  If -o is not specified, the case of the pattern
does not matter.

I have tested in both 2.5.4 and 2.6-cvs.
