... leave it in. JavaHL does not expose an experimental C API. It
exposes an editor interface that happens to currently depend on the Ev2
shims, but could in future depend on Ev3, or some other editor
interface, or shims local to the JavaHL implementation.

The point is that the JavaHL editor, as currently used for commit and
status over RA (without the client layer), is much easier to use than
the delta editor.

Rewriting the implementation to use the delta editor directly would be
nothing more nor less than copying the Ev2 shim implementation into
libsvnjavahl, which doesn't make sense. The Java API itself is similar
enough to the current Ev3 design that it shouldn't be too hard to change
the implementation once Ev3 is done.

I'm strongly -1 to exposing the delta editor API in JavaHL; it's just
too convoluted.
