Before introduction of new --diff-merges options, --first-parent
implicitly changed the default diff format for merge commits to
showing only the diff with respect to the first parent, and there were
no way to get such format from "git log" without affecting history
traversal logic that --first-parent causes.
Now, after introduction of the --diff-merges=first-parent, the
--first-parent simply implies the former, and this patch corrects
documentation accordingly.
