If you know the ref, then git show <MERGE_COMMIT>
will show you the resolution done (if any) for the merge commit.
For log, use git log -p -c
or git log -p --cc
. From the manpage of git log:
-c
With this option, diff output for a merge commit shows the differences from each
of the parents to the merge result simultaneously instead of showing pairwise
diff between a parent and the result one at a time. Furthermore, it lists only
files which were modified from all parents.
--cc
This flag implies the -c option and further compresses the patch output by
omitting uninteresting hunks whose contents in the parents have only two
variants and the merge result picks one of them without modification.
