Add error handling to dsmc to avoid looping asking questions to non-existent terminal

dsmc does not handle End Of File (EOF) on stdin gracefully when the situation arises that it needs to prompt and ask a question. Instead of realizing that there is no terminal attached and abort gracefully it gets stuck in a loop forever saying:

The character '#' stands for any decimal integer.The only valid responses are characters from this set: [1, 2, 3, 4, A]

The correct (expected) behaviour is to realize that it has reached EOF on STDIN and treat it as the user has selected A for abort. There is no point in repeating the question as there will NEVER be any user present to answer it!

To easily reproduce:

dsmc restore /my/file < /dev/null

retrieve or restore a file twice with STDIN attached to /dev/null as shown in the example above. On the second attempt dsmc will try to prompt regarding overwriting the file and get stuck in a loop as described.
