So this is the key change. I am trying to work out what the actual
changes are here: in your commit message for the test update 7/9 you say
that the old code only output the first part. My impression of the
deleted code is that that is not the case (but I don't grok cl very
well).

I think the test change is because in show we do some content-type
guessing of application/octet-stream which the below doesn't do.

But we may also have some things with mm-inlined-types as mentioned in
my earlier reply. Anyway if you can point out any other cases where it
is changed that would be great.

If you go for a function deciding which parts to include then it might
be possible to have a midpoint where we are the same as before, and then
tweak the function to get whatever behaviour we think is best. That
might make it easy to see what is tidying/unification and what is
enhancement.

Incidentally, thank you for splitting this series so finely: I did find
that made it a lot easier to review.

Best wishes

Mark
