Long subject lines

OK, I'm a laggard, still on mutt 1.8.0, but when I compose a three-line
subject in vim¹, separated by newlines, it is visually _joined_ into a
single line on return to mutt. Sending it to myself, it is displayed as
three lines in mutt, but more compact than composed. That may just be
wrapping of the single line.

The only other MUA I have any familiarity with is ancient "mail", and it
shows the same for the received message.

Seeing three lines in vim being joined to one in mutt, I don't expect
vim settings to have much effect in the MUA.

My simple experiments suggest that it's just mutt joining vim's multiple
lines into one, then wrapping that for useful display on receipt.
