By default, `git log` does not generate any diff output. The options
below can be used to show the changes made by each commit.
-Note that unless one of `-c`, `--cc`, or `-m` is given, merge commits
-will never show a diff, even if a diff format like `--patch` is
-selected, nor will they match search options like `-S`. The exception is
-when `--first-parent` is in use, in which merges are treated like normal
-single-parent commits (this can be overridden by providing a
-combined-diff option or with `--no-diff-merges`).
-
--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.
-
---combined-all-paths::
- This flag causes combined diffs (used for merge commits) to
- list the name of the file from all parents. It thus only has
- effect when -c or --cc are specified, and is likely only
- useful if filename changes are detected (i.e. when either
- rename or copy detection have been requested).
-
--m::
- This flag makes the merge commits show the full diff like
- regular commits; for each merge parent, a separate log entry
- and diff is generated. An exception is that only diff against
- the first parent is shown when `--first-parent` option is given;
- in that case, the output represents the changes the merge
- brought _into_ the then-current branch.
-
---diff-merges=off::
---no-diff-merges::
- Disable output of diffs for merge commits (default). Useful to
- override `-m`, `-c`, or `--cc`.
+Note that unless one of `--diff-merges` variants (including short
+`-m`, `-c`, and `--cc` options) is explicitly given, merge commits
+will not show a diff, even if a diff format like `--patch` is
+selected, nor will they match search options like `-S`. The exception
+is when `--first-parent` is in use, in which case `first-parent` is
+the default format.
