[issue8355] diff.py produce unified format by default

[Eric Smith]

Eric Smith <eric at trueblade.com> added the comment:

This would be easier to review if the patch were generated with 'svn diff'.

That said, it looks okay in concept to me, although I couldn't apply it and test without manually mucking with the patch.

2.6 is in bugfix mode, so it can't be changed there. I added 3.2, since it should probably agree with 2.7.

What I can't answer is if this should actually be done. I don't know if anyone's relying on the current behavior. I do agree that unified diffs are more desirable.
