Then I suppose we should focus on naming merge commits with this property:

  A merge commit that is not TREESAME to its first parent (but is TREESAME
  to a later parent).

The part in parentheses may be optional, because a merge commit that is
not TREESAME to any parent will be included by every history mode.

In my latest attempt at documentation, I called these merges "diverters"
yet still used "--include-diversions". Here are a few other words that we
could use:

 * diverters or diversions
 * redirects
 * switches (think railroad switch). Synonym: exchange
 * detours

The "switch" or "exchange" words are probably bad because they have
noun _and_ verb forms.

Or we could look again at the history results as a whole to find
inspiration for the command-line option:

 * --merge-trail

Thanks,
