+Tag rename unfinished business
+(things resulting from searching for `tag' where searching for
+ `debiantag' wouldn't find them)
+
+ - protocol version 4
+ implies ability to sign new tag (this is already there
+ so simply advertising version 4 will work)
+ needs also new ability to sign old-format tag in split
+ brain way
+
+ - many actual tests
+
+ - other tag should be [dgit Maintainer-Tag quilt=$quilt-mode]
+
+ - in dopush (?), we need to sort out synthetic fast forard
+ this should not depend entirely on quilt mode
+ but will always be needed if quiltmode_splitbrain
+
+ - there is some confusion between $split_brain (did we actually
+ generate any commits) and quiltmode_splitbrain (might we have done,
+ including in previous pushes); search for $split_brain and check
+ that use sites are correct
+
+
+Want tests for
+ - start repo with old tag, push with new tag, run
+ "old" dgit to push again with new tag, push again with
+ old tag
+ - rejecting push of same version with one tag when then the other
+
+That, where appropriate, maint view tags are pushed to dgit git repo
