    I cannot think of a string that has its length to be -ve. How would
a string of length -1 look like (as if that makes sense !! ) ?

     With the whole lot of string manipulation functions expecting a
pointer to the beginning of the string , to have strcpy / strcat return
pointer to the beginning of the string would be orthogonal to the API,
instead of other ways like pointing to its 'end' etc.
