Thanks for applying the patch.
Sorry the late reply.

In main, resolving.

Thanks for this.

I modified it slightly, and pushed it to crew (a3fd4aa154af). I hope you don't
mind that I didn't push the original but didn't modify the author.

I'm updating the status to reflect the proposed patch.
The patch is built against the main repository, it applies cleanly to the crew 
repo.

Resubmitting the proposed patch, used white spaces instead of tabs.

notify::diff() keeps line breaks in the diff buffer before calling
patch::diffstat().
patch::diffstat() adds another line break when feeding diffstat input.
This combination results in an extra empty line in diffstat input, leading to 
erroneous diffstat output.
To reproduce: a one line diff in a file is most of the time ignored (diffstat 
outputs '0 file changed'), the stats are otherwise inaccurate.
The proposed patch in attachment the line breaks in notify::diff() and loops 
through the diff lines to print them.

Cheers,
Divy
