Only 'cuz I didn't know any better. The Python SWIG bindings are
doing just that -- using the svn_delta_editor_t returned by
svn_delta_default_editor() as the "base class" and overriding all
functions except apply_text(). Simply cutting and pasting from
swigutil_py.c editor factory function corrected things.
There does seem to be some amount of duplication between the swigutil
lib for Python and Java (no suprise since I just copied the Python
version to get the Java version started). I suppose we'll eventually
want to factor out the commonalities, but I personally have a bit of a
mental block when working on this code with so many different layers
and technologies floating around.
