What kind of MUA are you using that mangles quoted mails like this? I've
not seen it on intel-gfx before. mesa-dev seems rife with it, but as I
rarely read that in any great detail I've managed to ignore it there.
Anyways, it makes it espesially hard to navigate long mails since mutt's
'S' (skip quoted text) no longer works correctly.
Not sure I want to say, and get booted out the door :-)
I've heard that gmail has an annoying habit of forcibly wrapping plain text emails like this, and a lot of people have complained that there's no way to disable that 'feature' :-/
I used to use Mutt, but I don't think I could really bare to go back to it any more. Last time I was using it I found myself spending too much time patching it to try and make it work how I'd like, but can't say I got much enjoyment from that process.
I've tried most MUA options available, and can't say any of them make me very happy - I think these days it's just not something developers are very interesting in working on.
I'm a sell out and just use Gmail... sorry. I can't really see myself changing, though I do wish Google weren't so pedantic about forcing wrapping without any option to change that behaviour. I suspect you wouldn't be happy with me sending html emails, which has been Google's default response to this complaint afik.
Maybe it's gmail users causing trouble on the Mesa list too.

P.S please don't think lesser of me due to my misguided MUA choices.
