There are three situations for a merge commit:
1. TREESAME to _all_ parents. These are not included.
2. not TREESAME to _all_ parents. These are already included.
3. TREESAME to some, but not TREESAME to others.
The third mode is the one that default mode will drop, but --full-history
will include. The new mode will include some of these (the ones that are
NOT TREESAME to their first parent).

The merges do something meaningful: they "merge in" a "real" change.
I'll just submit my v2 as-is, which includes a significant change to
the documentation that should make things more clear.
