As of this commit, the cannonical way to retreive an ANSI-compatible
color escape sequence from a configuration file is with the
`--get-color` action.
This is to allow Git to "fall back" on a default value for the color
should the given section not exist in the specified configuration(s).
With the addition of `--default`, this is no longer needed since:
$ git config --default red --color core.section
will be have exactly as:
$ git config --get-color core.section red
For consistency, let's introduce `--color` and encourage `--color`,
`--default` together over `--get-color` alone.
