Re: [PATCH 2/2] --date=relative falls back to "short" format for commits older than a year

Subject: Support 'raw' date format

Talking about --date, one thing I wanted for the 1234567890 date was to
get things in the raw format. Sure, you get them with --pretty=raw, but it
felt a bit sad that you couldn't just ask for the date in raw format.

So here's a throw-away patch (meaning: I won't be re-sending it, because I
really don't think it's a big deal) to add "--date=raw". It just prints
out the internal raw git format - seconds since epoch plus timezone (put
another way: 'date +"%s %z"' format)

Not a whole lot of testing. But

       git show --date=raw v2.6.29-rc5

works correctly.
