Well in our workflow each series has at least one merge commit.
(You *could* have different descriptions for the different branches,
e.g. for maint: "fixes a segfault so let's get this in, but it needs to be
redone properly" and for pu: "TODO: revert this partially
when branch $proper-fix is merged")

We could suggest to use a merge always strategy for this, i.e. as soon as
you send a cover-letter, we'll make a merge for you whose parents are the
old HEAD and the new series?

If the user strictly wants to have a linear history, then we could try some
empty commit magic before or after the series, but I doubt this is proper.

If users insist on linear history, they deny the benefits of a DAG that
represents how the source code evolved. (Also see the eternal rebase
vs merge discussion ;)

"besides the description"?

What do you mean by that?
