I don't think it should be turned on unconditionally, since it does
require some more work to generate the log, but I see no reason why we
couldn't add an option for it.

The patch below should cause the log to be generated with "--follow",
but obviously it needs more work to be turned into a proper patch.  If
this is useful I'll try to find some time to do this properly.
