Thanks for your detailed investigation, Mark.  
I may have misremembered how a previous posting of mine was mis-indented
(...postings were from a few years back, and it may have just been that
my replies were shown at the top level instead of indented - I believe
this may have been an old bug with Outlook specifically).

I don't have any other examples from other mailing lists, so let's
assume it's just the twistedmatrix.com list for now.
I'll forward this thread to their mailing list administrator to

Thanks again for your help.
