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.
