+ Improvements:

+
+ Documentation:
+ * dgit(1): Remove some obsolete caveats from BUGS.
+ * dgit(1); Mention that -wgf can avoid need for build-deps.
+ * dgit(1): Reorganise and complete the configuration section.
+
+ Useability improvements:
+ * Provide -wdd aka --clean=dpkg-source-d. Closes:#792433.
+ * Provide -wc aka --clean=check.
+
+ Access machinery:
+ * Remove configuration relating to alioth.
+ * Provide for different access mechanisms when pushing.
+ * Provide for configurable git url suffix.
+ * Allow git-url to be '' to force fallback to git-proto etc.
+ * Provide for checking git presence via http[s].
+ * Do some quoting on debug output (needed if the server might not
+ be trustworthy and might send us bad stuff).
+ * Talk to push.dgit.debian.org, rather than the .debian.net alias.
