Please show a test case including files to compare and command line used.
Comment 2 h4ck3rpunk 2011-03-25 19:27:08 UTC 
Sorry... I'm new

diff -rupN Release_5.5/ WonderQVM-v1.0/ > wonderland.patch

...is the command I used. The file shows the entire original file as red and the new file as green (might have that backwards...) I'll attach the .patch.

I tried making a patch between wonderland qvm and lakitu7qvm

Does not find any similarities. I used: 

diff -rupN Release_5.5/ WonderQVM-v1.0/ > wonderland.patch
Comment 4 Tim Waugh 2011-03-28 12:18:34 UTC 
Thanks for the report.  On this occasion it isn't really a bug.  One of the files uses CR-LR line termination, while the other does not -- so the files are in fact entirely different.  Use the option --strip-trailing-cr to see differences other than line termination differences.

Oh thanks! Sorry about posting a nonbug.
