r522:    * Set DH_ALWAYS_EXCLUDE=CVS and debhelper will exclude CVS directories
     from processing by any command that takes a -X option, and dh_builddeb
     will also go in and rm -rf any that still sneak into the build tree.
   * dh_install: A patch from Eric Dorland <eric@debian.org> adds support for
     --sourcedir, which allows debian/package.files files to be moved over to
     debian/package.install, and just work. Closes: #146847
   * dh_movefiles: don't do file tests in no-act mode. Closes: #144573
   * dh_installdebconf: pass --drop-old-templates to debconf-mergetemplate.
     Means debhelper has to depend on debconf-utils 1.1.1.
