Scratch that.  On further thought, these also look correct.  I wasn't doing the capturing in my head correctly.  So I
thinkthe patch is working!  I'll test a bit longer. 

Is this patch (alternate-backref-corner-case-fix-1.patch) the current state of your patch set?  I'd like to be sure I'm
testingyour latest work.  Thanks.
