My understanding is that the succession of events went stg like:

1) invent the rename detection, but consider it experimental
   hence don't activate it by default;

2) add commands using the rename detection, and since it works
   well, use it by default;

3) activate rename detection by default for diff.

The next logical step is what you patch does indeed.

That init_diff_ui_defaults() should indeed have been before
git_config() from the beginning. My bad, I'm the one who
misplaced it apparently :-(.

This "break_opt = 0" deserves a mention in the commit message
IMHO. I'm not 100% sure it's a good change actually.

break_opt is normally controlled by "-B/--break-rewrites".
I'm not sure why it was set to 0.
