Inki,

I haven't heard back from you on whether or not you want the bindings
patch to be included with me resending the series as V7 or if you're
OK with a single, stand-alone patch.
Will you let me know?  I have the patch standing by waiting for
instructions.  If you're not the right person to ask, please let me
know who the right person is.

thanks
