This wont work on system V (since -r is not an option to tail) and probably 
wont work on most other unixes if the file is large since tail will only read
the last block (not sure of exact size) of the file.

This is the problem when you want to get the last 1000 lines in a file of 
80 character lines.  I haven't found a standard tail that will properly 
handle this, but I have written one.
