I have 2.10 here, so maybe this was fixed later, but I don't see
renames followed when -L is used.  E.g., try this:

  git log -L77,83:admin/charsets/Makefile.in

You will see Git claiming the only version which changed that is the
one in which Makefile.in was created from Makefile.  Am I doing
something wrong, or expecting too much?
