+ Important bugfixes to other components:
+ * dgit-repos-server: Do not reject commits with no author/committer
+ email address (but still insist on date, and hence on the actual
+ committer and author commit header fields). Peter Green reports that
+ eg 66c65d90db100435 in upstream linux.git is such a commit (and is
+ accepted by github). Closes:#863353.
