Re: [PATCH 1/4] builtin/config: introduce `--default`

In an aim to replace:

  $ git config --get-color slot [default] [...]

with:

  $ git config --default default --color slot [...]

introduce `--defualt` to behave as if the given default were present and

s/--defualt/--default/

assigned to slot in the case that that slot does not exist.

Values filled by `--default` behave exactly as if they were present in
the affected configuration file; they will be parsed by type specifiers
without the knowledge that they are not themselves present in the
configuraion.

Specifically, this means that the following will work:

  $ git config --int --default 1M does.not.exist
  1048576

In subsequent commits, we will offer `--color`, which (in conjunction
with `--default`) will be sufficient to replace `--get-color`.
