Tell a command that renders into a view how wide that view is, through
COLUMNS. git reads it in preference to the size of the terminal it is
talking to, so the diffstat now fills the view whether or not the render
has a terminal to offer.
A diff renderer that can't ask a terminal gets the width from it too;
difftastic, diff-so-fancy and delta all support COLUMNS, so we can stop
running git in a PTY and these will still work.
