Okay, good one.  Here's how it works now.

    ## If updating, skip any that are unchanged
    next if how == :update and
            File.exists?( full_out_path ) and
            File.mtime( path ) < File.mtime( full_out_path ) and
            ( vars[:page].updated.nil? or
              vars[:page].updated < File.mtime( full_out_path ) )


So, it'll update if:

   1. No corresponding page is found in your output directory.
   2. A page is found, but it's older than the template it's based on.
   3. A page is found, but it's older than the latest updated entry on
      the page.
