OK.

Yes, it worked fine!  :D

BTW, there was an individual who reported a regression back in May on the
very same commit.  I was not able to get him to participate in the process
of tracking this down, but he did (suddenly) write a post on his blog a
couple of days ago that he had success using some unspecified git tree HEAD.

I believe that was probably the patch that you have reverted, so once I
know that a new candidate is in place I will let him know on his blog and
see if I can talk him into trying it.  This has been a month-long quest
for me -- beginning on Aug. 4 -- and I can understand why he gave up in
May without resolving the issue.  It's too bad for all of us that he didn't
pursue it then, huh?

Thanks,
Dave W.
