Re: Adding color to git diff output.

What I have is a script ~/bin/gitcdiff:

And then setting GIT_DIFF_PAGER="~/bin/gitcdiff".  When piping to a file 
it just uses cat, but when the output is a terminal device it uses the 
colordiff.

I thought about integrating that logic into git-diff.sh, but i'm not sure
it's always appropriate.

Yeah, that's close to what I'd have suggested:
