+ By default, colors are shown only when enabled for log output (by
+ `color.diff`, `color.ui`, or `--color`, and respecting the `auto`

+ is accepted as a historical synonym for the default (e.g.,
+ `%C(auto,red)`). Specifying `%C(always,...) will show the colors
+ even when color is not otherwise enabled (though consider
+ just using `--color=always` to enable color for the whole output,

- '%m': left (`<`), right (`>`) or boundary (`-`) mark
- '%n': newline
- '%%': a raw '%'
- '%>>(<N>)', '%>>|(<N>)': similar to '%>(<N>)', '%>|(<N>)'
respectively, except that if the next placeholder takes more spaces
than given and there are spaces on its left, use those spaces
-- '%><(<N>)', '%><|(<N>)': similar to '% <(<N>)', '%<|(<N>)'
+- '%><(<N>)', '%><|(<N>)': similar to '%<(<N>)', '%<|(<N>)'
respectively, but padding both sides (i.e. the text is centered)
-- %(trailers): display the trailers of the body as interpreted by
- linkgit:git-interpret-trailers[1]
+- %(trailers[:options]): display the trailers of the body as interpreted
+ by linkgit:git-interpret-trailers[1]. The `trailers` string may be
+ followed by a colon and zero or more comma-separated options. If the
+ `only` option is given, omit non-trailer lines from the trailer block.
+ If the `unfold` option is given, behave as if interpret-trailer's
+ `--unfold` option was given. E.g., `%(trailers:only,unfold)` to do
+ both.
NOTE: Some placeholders may depend on other options given to the
revision traversal engine. For example, the `%g*` reflog options will
