Subject: pass struct commit to diff_tree_combined_merge()
X-Git-Tag: v1.7.9-rc0~21^2~1
X-Git-Url: https://git.tokkee.org/?p=git.git;a=commitdiff_plain;h=82889295e76200714d76e0f7beb07b6b9e3b5a88

pass struct commit to diff_tree_combined_merge()

Instead of passing the hash of a commit and then searching that
same commit in the single caller, simply pass the commit directly.
