The inn package doesn't package most of the contents of
share/examples/inn, but attempts to use them in exec/unexec portions
of the package list, producing errors for binary package installations
on systems where there is no existing configuration in
/usr/local/news/etc.  Users looking for an example configuration
installed by the package won't find one.

    There are some indications of intent here, but I can't figure out
what it was: with the fix below, the plist line 

@unexec for f in %%ETCFILES%%; do rm -f %D/%%EXAMPLESDIR%%/${f}; done

    is presumably redundant.  However, the ETCFILES don't exist in the
package at all, so I'm a bit puzzled how this line did anything
useful previously.

Fix: Apply patch below, and rebuild package.
