Subject: checkdiff: pass diff_options to the callback
X-Git-Tag: v1.6.0-rc0~175^2~4
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=1ba111d1d6bd90b2c120ceb05418e01ee304cc46;p=git.git

checkdiff: pass diff_options to the callback

This way, we could later use more information from the diff_options.
