- COMMON DIFF OPTIONS
- -------------------
+ DIFF FORMATTING
+ ---------------
+
+ 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::
+ --diff-merges::
+ 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 Formatting
- ~~~~~~~~~~~~~~~
-
- Listed below are options that control the formatting of diff output.
- Some of them are specific to linkgit:git-rev-list[1], however other diff
- options may be given. See linkgit:git-diff-files[1] for more options.
-
- -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.
-
- -r::
- Show recursive diffs.
-
- -t::
- Show the tree objects in the diff output. This implies `-r`.
