"Question?" is maybe not the most informative thing to ask. In the absence of better information, it is the best we can do, of course.

However, Git for Windows' auto updater just learned the trick to use git-gui--askyesno to ask the user whether to update now or not. And in this scripted scenario, we can easily pass a command-line option to change the window title.

So let's support that with the new `--title <title>` option.
