I don't know if it should be *that* mechanical; there are a lot of places 
where I've seen " 'something %s' % repr(foo)" when I think it's much more 
clearly written as " 'something %r' % foo".  I don't know which is the 
officially preferred style, but if it's the latter (and I hope it is ;)) then 
it may not be good to mechanically change backticks to a repr call.
