That's when the Copyright notices were updated for all the files,
to include 2011, because a new year has begun.  What was the problem
with these lines?

So what is the problem here?  If every file has its first line or two
changed, the diff of 6MB is normal.

"bzr diff" always diffs against the current version by default, which
you can see with "bzr revno".  If you give non-default -rREVNO
arguments to "bzr diff", then presumably you already know the
revisions yourself.
