Subject: diff-options: add --patch-with-stat
X-Git-Tag: v1.3.0~17
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=293532739415d287786a312ec10849723383796e;p=git.git

diff-options: add --patch-with-stat

With this option, git prepends a diffstat in front of the patch.

Since I really, really do not know what a diffstat of a combined diff
("merge diff") should look like, the diffstat is not generated for these.
