annotate svnwrap/svn_swig_wrapper.py @ 298:32d3f1716e66

Two minor optimisations/cleanups for svn_swig_wrapper: - 'self' is not used in 'RaCallbacks', so use the @staticmethod decorator syntax introduced in Python 2.4. - Make 'Revision' derive from 'tuple' and use property getters to obtain the individual values. In N+1 years, we can use the NamedRecord introduced in Python 2.6.
