hrmmm..... I'm realy not sure that translators will be able to properly understand that `%(percent)s%` is the variable, AND THEN the SECOND `%` is the literal percent sign. I am a bit fuddled as to why {percent}% won't work.

When do you need to merge this in by? I might be able to find some time Thurs or Friday to do a little bit of digging on this.
