The trade-off is that you have to read the entire file in order to
verify the checksum.  Since SCCS has to read the entire file anyway,
there's no additional overhead.  RCS, on the other hand, doesn't have to
read all of the diffs, particularly if you're just checking out the head
revision which, in the RCS philosophy, is by far the most common
