- adding `auto,` at the beginning will emit color only when colors are
- enabled for log output (by `color.diff`, `color.ui`, or `--color`, and
- respecting the `auto` settings of the former if we are going to a
- terminal). `auto` alone (i.e. `%C(auto)`) will turn on auto coloring
- on the next placeholders until the color is switched again.
