[bug #12995] grep with --color and -i causes color match not to be displayed

[Benno Schulenberg]

Follow-up Comment #3, bug #12995 (project grep):

This seems to be fixed in CVS.  At least, I cannot reproduce your results
with grep from CVS, nor on Ubuntu Edgy, nor on a current Gentoo installation.
 Your Knoppix is somewhat old; please retry with a later version.

echo "a A a A" | grep -o  a
echo "a A a A" | grep -io  a
echo "a A a A" | grep -o "[aA]"
echo "a A a A" | LC_ALL="en_US.utf8" grep -io  a

Only with an unpatched grep-2.5.1a can I reproduce the non-matching
behaviour; but then also the setting of LC_ALL="en_US.utf8" does not mask the
bug.

(In future: do not add to bugs that look similar, but create a new bug
instead. Leave it to the maintainers to mark bugs as duplicates where
necessary.)
