[PATCH] rebase: only show stat if configured to true

If rebase.stat is set to true, a diffstat should be displayed. If it is
not set, it should default to false. However, if it is explicitly set to
false (or other value), a diffstat is still displayed, which is probably
not what most users would expect. Show diffstat only if it is set
to true.
