I'm working on some shonky C code at the moment that inconsistent  
indentation and very long lines.  It is extremely annoying not to be able  
to put the original code, my "translation" and sundry utilities all  
side-by-side on the same screen (and it's not a particularly small  
screen), and having to keep flipping between them slows me down  
dramatically.  Long lines have no effect on the speed of the program, but  
they can have serious effects on the speed of the programmer.
