Thank you for taking care of that for me.  Could you also commit the
following bugfix to my code?  The bug showed up when you have multiple
vc-annotate buffers open; I was using `make-local-variable'
improperly; that is, it wasn't being evaluated in the buffer that
actually needed the buffer-local variable (that being the annotate
buffer).

Thanks,
Benjamin Rutt
