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.

A user or a package might have configured their Emacs such that new buffers
aren’t shown in new windows, but in new frames, for example, and undoing that

just assuming “pop-to-buffer”.
Indeed, that would complicate the "undo" logic. Especially the "new
frames" part.
.05s, I’d say. My “git diff” is way faster than that for a file that hasn’t
changed.
We also have vc-root-diff, which handles the whole repository, and not
just one file. It would be desirable for the to behave similarly.
No, just git-diff.
Why just Git?
I can change it back to synchronous for the mentioned backends (Git, Hg, RCS)
now; that's simple. The more advanced solution will have to be written by
someone else then.
I would probably change it back for 25.1,
I've reverted it for Git, Hg, MTN and RCS now, which should bring them
to the Emacs 24 behavior.
and then someone (who’s the VC maintainer?)
Take a guess.
You can have this honor, if you like.
