I've thought of a reason that this is the wrong thing to do...
(the numbers are changesets)
merge(6) re-merge(7)---new mainline----
\ / /
Once you do the re-merge, you should mark changeset 6 (the first merge)
as non-exported. But that doesn't mean the branch line containing
changeset 5 shouldn't be exported. In fact, it might well be the
maintainer has specifically requested that she do all merging, and
doesn't want to pull merges from other people's repositories. So any
merges you do are for your own benefit and not 'official'.
So, you should be able to mark changeset 6 as non-exported without
having any effect on the exportability of anything else. You could
solve this by saying a non-exported head only effects the exported
status of until the first changeset with more than one parent, but that
doesn't feel right either.
Marking a changeset as non-exported and having it effect all changesets
that depend on it is a better solution. If some other repository got
that changeset before you marked it then they have it, but can't get any
of the updates that need the non-exported changeset until you mark it as
