Please see the bug report below. In short, when using --partial together
with --update, an interrupted file will get the current timestamp, and
hence when redoing the transfer the file is skipped due to --update.
I've created a patch that sets the timestamp to 0 when a file transfer
is interrupted, which was suggested by the bug reporter and sounds
sensible to me.
Any possible hidden gotcha's?
