Makes sense.

One slightly less boring case.  Is it possible to merge when the
simplified history, looking only at changes outside the narrow tree,
would have permitted a fast-forward?

If so, a git contributor who is only interested in Documentation/
could work on "next" between releases and keep up with "maint" and
"master" longer term, without the help of a full-tree-merging machine.

More realistically, a linux-2.6 contributor only interested in one
subsystem could always keep up with "master".  Which would be nice.
