It might be easier for people to follow the substance of this thread
if you posted in such a way as to include one simple self-descriptive
test in each post, and not include all the deeply-nested "noise" like
the above. So, for example, you could write:

>From foo. This line was written with a leading unescaped From, "From ".

>From bar. This line was written with a leading escaped From, ">From ".

You could, in addition, include a file attachment of the test as written.

You might also wish to omit/change your Attribution line temporarily,
because it prevents your tests from ever consisting entirely of 7-bit
ASCII, owing to its "à".

These little things might help clarify your reports of the distorting
effects of a medium, when those reports are subject to the same
potential distortion.

Cheers,
David.
