This paragraph of yours is wrapped fine by notmuch show, but
this is to expect, it's merely a single long line.  I do not
re-fill it here.

f=f is different though it:

1. f=f renders paragraphs with soft line breaks thus every
   email client should be able to show it even if not able
   to grok f=f.
2. f=f enabled mail clients are not only capable of
   re-flowing the paragraphs to the window size, but even
   quoting in several levels is preserved while reflowing
   the paragraphs

I re-filled your last paragraph.

I fiddled around f=f several years ago and found

a. support in email clients to be lacking
b. f=f does not support, but to the contrary ruins, plain
   lists and indented paragraphs.


Points a. and b. were deal breakers for me and so I stay
with hard line breaks till today.  But since I want my
emails to be readable even for people on mobile devices I
opted for short lines.  Thus your screenshot is really
helpful for me.

Have a look for yourself, ciao; Gregor
