[PATCH v3 0/4] Teach `--default` to `git-config(1)`

Hi all,

Attached is 'v3' of my patch series to add a `--default` option to `git config`.

The most notable change since the last reroll is that this series is now based upon tb/config-type-specifier-option [1], with discussion about that change here [2]. This was motivated by my and Peff's shared concern that by adding `--color` as a top-level type specifier, that we'd be "squatting" on adding `--color` in the traditional sense of "colorize this output."

As such, `--color` is _not_ added as a top-level type specifier in this version, rather, it is accessible via `--type=color`. This leaves `--color` unused and available for other uses in the future.

Other changes since last time include:

  1. Fixing an erroneous diff in Documentation/git-config.txt, where a header
     was removed.

  2. `git config` will now die immediately when the `--default` value is not
      canonicalize able under the given type specifier.

  3. Removing redundancies from t1300 and t1310 that are--as Peff wisely points
     out--unlikely to catch any meaningful regressions in the future.

  4. Documenting behavior in builtin/config.c that we "throw away" the
     canonicalized value during normalization.

As always, thank you for the helpful feedback. I look forward to your thoughts on this version of the series.

Thanks, Taylor
