Yeah, true.  Perhaps the simplest way to do this is for the yum plugin
to pass down the paths that matched?  Another alternative would be for
the the actions themselves to be Python code, and we just do the
equivalent of:

for plugin in plugin:
  plugin.run(package_name, changed_files_list)

Something to figure out for when this gets pushed into RPM.
