OK, that part of the motivation I completely missed.  If end-users
and scripters are happy with the behaviour of --get-color that does
not terminate its output with LF (which I think is a reasonable
thing to do, as "color" is special in that context, i.e. having a
dedicated --get option suitable for that type), as we advertise
"--type=color" is the same as "--get-color" (only better), we need
to special case it, and omitting LF at the end similarly does make

Now I think "we weren't consistent to begin with with --get-color,
and treating --type=color as a special case is justifiable"; and I
agree with the above two points.
