[Bug report] No color in grep (grep (GNU grep) 2.5.1) when used with -i

[Sylvain Desodt]

Hello everyone,

I just had a problem with grep : the color does not seem to work when
performing case-insensitive searchs.

Here is a simple piece of code to see the problem :
% echo -ne "a\nb\c\ndef\nDEF\ng\nh\n" >! grep_test # creating a test file
% grep --color=always E grep_test # finds the right line and colors the pattern
% grep --color=always E -i grep_test # finds the right lines but no
color for the patterns

I found other people with the same problem (
http://superuser.com/questions/73261/grep-colorauto-with-i-option-disables-the-matching-text-color-why
) but I don't know if you are aware of the problem. Sorry for the
inconvenience if you already knew about it.

Some more information about my configuration/system :

% grep -V
