I agree the defaults need changing at some point --- and it might as well
be now for the reasons you give. This turns them on by default (I got a
little confused between $lfs and $enable_lfs, but that's par for the
course) and changes INSTALL accordingly. Ideally, turning on large file
support should be completely transparent. Ha.
