Well it doesn't have a bug, it was intended to reverse
seven bits and not eight. I'm no Payson, but it looks
like for one more cycle you could do this:

        rrf     source,w
        rrf     source,w
        btfsc   source,0
         xorlw  h'41'
        btfsc   source,6
         xorlw  h'41'
        btfsc   source,1
         xorlw  h'22'
        btfsc   source,5
         xorlw  h'22'
        btfsc   source,2
         xorlw  h'14'
        btfsc   source,4
         xorlw  h'14'
