actually it should work as described in the manpage

SEPARATORS:
  _ (underscore)  
             neutral separator
  + (plus sign), _and_  
             conditional AND
             the next command will only be executed if the previous succeeded
  - (minus sign), _or_  
             conditional OR
             the next command will only be executed if the previous failed

   example:  
    'pre+bkp-verify_post' translates to 'pre_and_bkp_or_verify_post'

if not it's a bug and should be fixed. ..ede/duply.net
