This is a carry-over  from the '60s when computers had 
typewriter-like devices as a console printer or output device.

A big break-through was the invention of the IBM Selectric "Golf 
Ball" typewriter printer.

This device could advance the platen (line feed) separately from 
returning the carrier (the golf ball print head) to the left margin.

So, if you were printing a column of numbers starting in position 40, 
you would:

    print a number
    backspace (the length of the number of characters in the number 
just printed)
    issue a line feed

    Repeat the process

as opposed to:

    Tab
    Print a numrer
    Issue a carriage return, Line Feed

    repeat the process

The former process was about 10 times faster than the latter process,,,
