I think your answer might not be high-level enough.

That said, if you want to compute the delta between two versions, it'll
be easiest to just do what 'svn update' does. svn_ra_do_update2() or
svn_repos_dir_delta2() (but see comments in its doc string) might be
good places to start.

Or you could 'svn cat' twice and then pass the result to an svn_delta.h
