I read through the thread and it seems to me that in essence a special empty
commit was suggested to be used to a similar effect. I think instead of using
a "magic" commit directly in the DAG, it would be much cleaner to store this
separately in a special "branch note". "format-patch" and "am" could be taught
to handle it automatically. I do really like the idea of having a special
syntax in the note to that would delineate the branch description proper (which
could go into a merge commit) from respin versioning of a series.

It could also serve as a nice and built-in way of sharing information about
more permanent branches, e.g. the git project could publish via this special
branch note some of the info about next and seen, that is now somewhere in the
documentation. Forges could easily display it and it might also make it easier
to discover how a repository is structured after cloning.
