   1--summary::
   2        Show a diffstat at the end of the merge. The diffstat is also
   3        controlled by the configuration option merge.diffstat.
   4
   5-n, \--no-summary::
   6        Do not show diffstat at the end of the merge.
   7
   8--no-commit::
   9        Perform the merge but pretend the merge failed and do
  10        not autocommit, to give the user a chance to inspect and
  11        further tweak the merge result before committing.
  12
  13--squash::
  14        Produce the working tree and index state as if a real
  15        merge happened, but do not actually make a commit or
  16        move the `HEAD`, nor record `$GIT_DIR/MERGE_HEAD` to
  17        cause the next `git commit` command to create a merge
  18        commit.  This allows you to create a single commit on
  19        top of the current branch whose effect is the same as
  20        merging another branch (or more in case of an octopus).
  21
  22-s <strategy>, \--strategy=<strategy>::
  23        Use the given merge strategy; can be supplied more than
  24        once to specify them in the order they should be tried.
  25        If there is no `-s` option, a built-in list of strategies
  26        is used instead (`git-merge-recursive` when merging a single
  27        head, `git-merge-octopus` otherwise).
