Having doubts about generate_checksums

If I edit /etc/pov/backup and add new things to back up, and re-run
pov-simple-backup -s, it would currently keep old SHA256SUMS files
that would not list the newly-backed-up things.

Also I've seen situations when interrupting encryptdir.py with ^C would
cause the script to go ahead and continue running, generating SHA256SUMS
even if several files are missing.
