Subject: [PATCH] copy: Avoid potential divide by zero when source size is zero

Actually this does not happen because of the way the progress bar is
called from other code, but it's possible that a future change might
introduce a bug, so avoid any problems.

(cherry picked from commit 266c6e7083b1e0e8373ce166cf0be388604ca805)
