diff-merges: let new options enable diff without -p
New options don't have any visible effect unless -p is either given or
implied, as unlike -c/-cc we don't imply -p with --diff-merges. To fix
this, this patch adds new functionality by letting new options enable
output of diffs for merge commits only.
Add 'merges_need_diff' field and set it whenever diff output for merges is
enabled by any of the new options.
Extend diff output logic accordingly, to output diffs for merges when
'merges_need_diff' is set even when no -p has been provided.
