Git diff with line numbers (Git log with line numbers)

When I do a git diff or a git log -p, how do I get line numbers of the source file(s) inlined with the output?

I just wrote git diffn over the last few days to be a drop-in replacement for git diff on the command-line. Give it a shot. See my other answer here.
