Its actually not your patch, which I've not yet received, and which I
agree with you should be kept out of stable.  I did decide to fix that
bug you found -- the one you thought was critical, and I agree -- this
did not break the windows build, but rather the *features* change, but
only in a very simple and easily fixable way.  All should be well now,
or at least back to the same old mysteries.  Would appreciate

Take care,
