Well, I was hoping that Subversion might be able to do more optimal
diffs or, in the future, know more about the diff operation than just
the fulltexts. (I'm not sure how merges are going to work yet).

I was afraid of that. I wasn't sure whether Subversion could generate
the diffs server side or not. I wonder if it would be generally useful
for Subversion to support a client side cache for operations like this,
or when we are using the internal diff library, to generate the diffs
server side?

Well the plan was to look into the state of the SWIG Python bindings. I
was hoping to avoid any parsing of output from the Subversion API.
Other than the client.diff() command, I was able to achieve this. Is
there some way I can get at the internal diff library and access the
diff before it gets converted to the printable format?
Also, what's the bad rap on the bindings? For repositories like CVS
where no such API is available, I can understand the need for parsing
the output from the command line client. But why would I want to depend
on the text format API instead of the binding API?
