I can't necessarily answer all of your questions. As I saw it, this
email did NOT have format=flowed set in the headers. It displayed fine
in mutt, but not on my iphone. (I can't be bothered to fire up Mail.app.
Sorry.)

The 'reflowed' paragraph did have too many spaces over here.

Yes, there is a way to fix it. Mailing your sample paragraphs to myself
caused the same thing to happen. But, it's supposed to as I understand
f=f. Here's why. I think the spec states that if you have a line that
ends with space, the reader should reformat it. If your formatting is
important, then don't put a space at the end of those lines. Since your
numbered list has formating that you want to keep, remove the spaces
from the end of those lines.

So, you need to either remove those spaces with a quick search and
replace (or a macro) or set 'fo-=w' and reformat those lines. Note
however that when you do this, programs which can't display the full
width of your fixed formatted paragraphs are going to mangle the
display. I know my phone just did. (Presumably Mail.app gets this
right since it displays more than 80 columns).

What I can't answer for you is why, when you do that, mutt seems to
delete a space at the beginning of the indented lines.

My ultimate advice is to skip fancy formatting like that in email, and
just go with f=f. So, maybe set 'fo-=n'. (Also, check out the j
option. Nice for reformatting quoted text.)
