grep: bug with -i --color

[Egmont Koblinger]

Hi,

When using both the -i and the --color options of grep 2.5.1, and the
pattern contains at least one uppercase letter, the output is not colored.

Example: (^^^^ means highlighted text)

$ grep --color=auto nobody /etc/passwd
nobody:x:99:99:Nobody:/:/bin/sh
^^^^^^
$ grep -i --color=auto nobody /etc/passwd
nobody:x:99:99:Nobody:/:/bin/sh
^^^^^^         ^^^^^^
$ grep --color=auto Nobody /etc/passwd
nobody:x:99:99:Nobody:/:/bin/sh
               ^^^^^^
$ grep -i --color=auto Nobody /etc/passwd
nobody:x:99:99:Nobody:/:/bin/sh
                                (nothing is highlighted this time)


bye,
Egmont
