Subject: VC opens new window to display minimal messages

At some point on the way to Emacs 25, VC has begun creating new windows to display messages that would more appropriately fit into the echo area.

For example, you do C-x =, it’ll display a “no revisions between working revision and work file” message.  But that is shown in the echo area AND a newly created window.

The consequence is that the user has to get rid of the superfluous mini window.  Also, mistakes happen - i.e., opening a new file, the new buffer will display in a window that is only one line high, so one’s got to deal with that.

Bottomline, this shouldn’t happen.  Use the echo area appropriately unless there’s really something to display.
