to change for the dgit user.
New checks and improved behaviours:
+ * When running dpkg-buildpackage, cope if user specified -g or -G.
* dgit sbuild: check that the set of .changes files found is as we
expect, before calling mergechanges.
* dgit sbuild: Rename the used-up .changes files to `.inmulti' to
avoid accidental use of the wrong one (by software, or by users).
* dgit sbuild: Check that the binary .changes file doesn't contain a
.dsc.
+ * Introduce --rm-old-changes to delete previous builds' changes files.
+ * Remove any pre-existing _source.changes file before building source,
+ 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.
Bugfixes:
* When cleaning up after failed clone, stat the to-be-cleaned-up
