as a safety check.
* No longer tolerate a multitude of .changes files when doing push.
Instead, insist on a single one.
+ * dgit sbuild no longer deletes extranious .changes files; instead
+ we rely on --rm-old-changes, or failing that, fail early.
Documentation:
* Document the dgit-distro.DISTRO.quilt-mode config setting.
zealot is very slow and we need to give the other processes time
to rollback and release the lock.
* Test quilt single-debian-patch.
+ * Provide `tartree-edit gitfetchinfo' etc. to help with comparing
+ different test case git working tree tarballs.
