Recently, a clone initiated via git gui on Windows crashed on me due to
an "unknown variable cdone". It turns out that there is a code path
where this variable is used uninitialized.

Looking at the output of display(), it's not clear to me now the
function below could ever be called with total=0. But I can't delve into
it more deeply right now, and this seems like an obvious fix.
