Title:
  0 is returned when there is nothing to do

Status in binfmt-support package in Ubuntu:
  New

Bug description:
  I'm using Ubuntu 16.10 dev with binfmt-support 2.1.6-1 and on trying
  to remove a non-existent entry from the database a warning is being
  displayed but 0 is returned like in this example:

  root at ubuntu:~# update-binfmts --remove EXE /opt/wine-devel/bin/wine
  update-binfmts: warning: /var/lib/binfmts/EXE does not exist; nothing to do!
  root at ubuntu:~# echo $?
  0

  
  Additionally trying to add an entry twice for example with "update-binfmts --install EXE /opt/wine-devel/bin/wine --magic MZ" does not result in a warning that the entry already exists and 0 is returned too.
