Add graphical diffstat to commit view
The diffstat is calculated against the leftmost parent of the commit. This gives nice information for "normal" merges while octopus merges are less than optimal, so the diffstat isn't calculated for those merges. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
Diffstat (more/less context) (ignore whitespace changes)
