install/upgrade feedback suggestion

[RJVB (René Bertin)]

When doing an install or upgrade, the last terminal messages shown are usually

--->  Cleaning foo
--->  Removing work directory for foo

and then the port command can remain busy doing who knows what for long seconds. I know consciously that it's probably just doing a somewhat lengthy registry operation but I often cannot help but wonder why that delete operation is taking so long ("exactly what is it deleting?!")

Maybe 'base' could show an additional progress message showing that the delete operation has completed, something more or less to the point like Finishing up?

Note that a "request" ticket type is only for requesting a new port.
