`-U<n>`::
`--unified=<n>`::
	Generate diffs with _<n>_ lines of context. The number of context
	lines defaults to `diff.context` or 3 if the configuration variable
	is unset. (`-U` without `<n>` is silently accepted as a synonym for
	`-p` due to a historical accident).

`--inter-hunk-context=<n>`::
	Show the context between diff hunks, up to the specified _<number>_
	of lines, thereby fusing hunks that are close to each other.
	Defaults to `diff.interHunkContext` or 0 if the config option
	is unset.
