don't exclude depends that start with '|'

apt-cache reports dependencies that may be satisfied by one of multiple packages (and OR) as follows:

ssh-askpass-gnome
  Depends: libc6
  Depends: libglib2.0-0
  Depends: libgtk2.0-0
  Depends: libx11-6
 |Depends: openssh-client
    openssh-client:i386
...

Note the leading '|'. This, I think, means that the dependency can be satisfied by installing either openssh-client or openssh-client:i386.

With dotdepends 0.3.16, such packages with a leading '|' are not included in generated results but should be.
