notify::diff() keeps line breaks in the diff buffer before calling
patch::diffstat().
patch::diffstat() however adds another line break when feeding diffstat input.
The added extra empty line leads to erroneous diffstat output.
This fix removes the line breaks in notify::diff() and loops through the diff
lines to print them.
