It would be very handy if that could be extended to take into account
FAT filesystems, i.e. automagically set --modify-window=2 if it's
detected that you're writing to a FAT filesystem. It's basically the
same problem as detecting that you're writing to a filesystem that
doesn't support nanoseconds IMHO.
