ATM upon `get` of a file for which no remote in .git/config provides its content, git-annex spits out a message like

[[!format sh """

although those remote descriptions/names give an idea for an informed user, they do not event differentiate between regular and special remotes.  Special remotes could just be "enabled", some of them might even have `autoenable` set.  May be it could separate them and provide a message like

[[!format sh """
