``Branch`` formats can now be loaded lazily by registering a
``MetaDirBranchFormatFactory`` rather than an actual format. This will
cause the named format class to be loaded only when an enumeration of
formats is needed or when the format string for the object is
encountered. (Robert Collins, Jelmer Vernooij)
