Looks like it runs "auto-fill-mode". You can turn it off, or you can
adjust the column that it wraps with the "fill-column" variable.

Probably because of tradition. It's generally considered polite to wrap
your column somewhere between 72 to 78. The SMTP spec (RFC 821) says:

So there is a maximum, though it's about a 13 line paragraph (wrapped at
72).

Many email clients (including Thunderbird, which I'm using) use the
quotable-printable encoding to encode longer lines (which escapes the
line with an "=" if it's not meant to end). I guess this idea is to make
the raw text mostly readable but still unwrappable. I think it's quite
ugly, but it appears to be a pretty universal standard.
