1. By piping with grep --color=auto, grep itself does not "colorize" the
text. Instead, you need to use --color=always .

2. grep --color=auto or always colorizes by using Ansi escape
sequences. You need the AnsiEsc plugin with vim to handle them

3. AnsiEsc works best with Vince Negri's conceal patch. I've compiled a
"special" vim with VN's conceal patch which I've renamed to "cvim".

4. The following command takes the grep output and runs it through
conceal-patched vim with the AnsiEsc plugin:

grep --color=always PATTERN FILENAME_HERE | cvim -c 'AnsiEsc' -

The AnsiEsc plugin colorizes text according to ansi escape sequences;
you can get the plugin from:

http://vim.sourceforge.net/scripts/script.php?script_id=302 (stable)
http://ftpmysite.verizon.net/astronaut/vim/index.html#ANSIESC
(cutting edge)

You can get VN's patch from
http://groups.google.com/group/vim_dev/web/vim-patches as patch#14.
