[PD] diffing .pd files

[Hans-Christoph Steiner]

Does anyone have a method for diffing .pd files that produces useful  
results?  Basically, I don't think that pixel coordinates are important  
if they change (only if it changes order of execution), and usually  
when I diff a .pd file, almost everything has changed because of the  
coords.

I find adding this makes it more helpful:
"cvs diff patch.pd | grep -v connect | cut -d ' ' -f 1,3,6-99" but I am  
wondering whether anyone else has done anything along these lines.   
Ideally, I would love to see a visual diff for Pd.
