2016-06-22 15:16 AEST by Arthur Barrett - The included 'diff' is pre-diffutils 2.7, should we upgrade?

I've 'compared' the code with 2.7 and functionally it looks the same.

Our code has extra debugging and differences to redirect the I/O

But diffutils 2.7 is seriously old.

From 2.8 onwards though it uses a new file structure that seems reliant on some pre-parser (e.g.: int 
is lin).  Together this makes it almost impossible to merge.
