Updated out of storage messages
Made progress messages have a consistent style.
Removed `Error $status:` messages.

The `not` clause in the if statement consumes the previous commands
$status value. The workaround is to store the $status, and then do
comparison on the fake status value, and echo it.

This is a fair amount of work though, for something that is arguably not
needed. So, for now it's disabled. If, in the future, we need the exit
statuses, we can implement the above.
