    Remove old compatibility code from 2002
    
    At the time, there were two competing packages for French language:
    frenchle (aka french.sty), the historical one, and frenchb.ldf, the
    new kid on the block. I was difficult to know which one was loaded by
    babel, and frenchle did not define \og and \fg. Thus the need for our
    own definition.
    
    These were the good old days, but this time is gone for good.
