I think this is a useful change as I was caught out by the existing 
behavior recently when I quit send-email without sending any patches and 
the shell thought it exited successfully.

I'm not sure about this implementation though. If I send one patch and 
then quit it looks like it will still exit(0) as both $sent_any and 
$sent_all will be true. I think it would be better to count the number 
of patches sent and compare that to the total number of patches when 
calculating the exit code to use.

Best Wishes
