GREP_COLORS variable is not used by grep

[Αναστασίου Γεώργιος]

Hi,
I am using grep 2.14,and when i export GREP_COLORS="7",grep leaves the
default for colorizing when using grep.Alias has been made for grep with
grep="grep --color=auto".Tried to use GREP_COLOR instead,and it is working.
Can you help me with this?

Thanks,
Giorgos Anastasiou
