This is ok.

Maybe your .emacs got messed up.  So I closed this bug.
When you'll be able to reproduce it, please reopen again.

Subject: 23.2; [M-x grep] match no longer coloured by default

Today I upgraded Debian's Emacs package from 23.1+1-9 to 23.2+1-2.
After doing so, I noticed that M-x grep RET did not font-lock the match
area by default.  It *does* do so if I manually --color as an argument.

For example,

    -*- mode: grep; default-directory: "/usr/share/live-helper/helpers/" -*-
    Grep started at Tue May 18 21:11:13

    grep -nHr . -e LH_INITRAMFS --color
    ./binary_manifest:45:case "${LH_INITRAMFS}" in
    [...]

The LH_INITRAMFS on the fifth line has a blue background (the "match"
face) iff I add --color.  In 23.1 I didn't need to supply --color.

Note that in my environment, I have

    GREP_OPTIONS=--color=auto

Therefore, my initial guess is that Emacs is now calling grep
differently, or grep's --color=auto heuristic has changed recently.

I'm running GNU grep 2.6.3.
