   > This looks OK, but incomplete. When if you at 
`org.apache.maven.cli.MavenCli.logging(CliRequest)` in the block marked with 
`// LOG COLOR` you see duplicate code now. It is probably time to move that 
code out of `logging()` into `cli()`.

   Which one? This?

   I do not see this code duplicated somewhere else. There are other duplicated 
parts, however.
