+Every breakwater commit must be a merge.  In principle, this is not
+necessary.  After all, we are relying on the
+    [git-debrebase breakwater: ...]
+commit message annotation in "declare" breakwater merges (which
+do not have any upstream changes), to distinguish those breakwater
+merges from ordinary pseudomerges (which we might just try to strip).
+
+However, the user is going to be doing git-rebase a lot.  We really
+don't want them to rewrite a breakwater base commit.  git-rebase
+trips up on merges, so that is a useful safety catch.

 what about dgit view branch ?
 ideally, would make pseudomerge over dgit view
 would need to check that dgit view is actually dgit view of
   ond of our ancestors
 failing that first push will need --overwrite

+gbp uses "import" oddly but I'm tempted to use it normally here.
