When using the diff bundle, I know there are some minor differences between two files, but diff will mark the entire documents as the difference, even though maybe 90%+ of the lines are the same. FileMerge does the same thing.
This typically happens when the two documents have different line-endings. Could that be your problem?
Thanks, Robin, that was it. Somehow, my line endings got screwed up.
I did a "save as" over the original, and it now works.
