Subject: [PATCH 1/5] git-gui: provide question helper for retry fallback on
 Windows

Make use of the new environment variable GIT_ASK_YESNO to support the
recently implemented fallback in case unlink, rename or rmdir fail for
files in use on Windows. The added dialog will present a yes/no question
to the the user which will currently be used by the windows compat layer
to let the user retry a failed file operation.

Subject: [PATCH 2/5] git-gui--askyesno: fix funny text wrapping

The text wrapping seems to be aligned to the right side of the Yes
button, leaving an awful lot of empty space.

Let's try to counter this by using pixel units.

Subject: [PATCH 3/5] git-gui--askyesno: allow overriding the window title

"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.
