It is from RFC2045 (MIME), whereas f=f is the lesser-supported RFC3676. Doing a search of my maildir, I find a large majority of them contain it. To test this, I'll be sending this message without hard-wrapping and with the Q-P encoding. If it shows up fine, I think I need to `edebug` the Emacs MIME library to find out exactly what's going wrong.

Indeed, f=f is better in many ways -- it's just that Gmail doesn't
support it so I want to work around that.

Glad to help. It seems like the web interface wraps my email fine (as
well as my phone, as expected), so I'm going to try to dig into this
MIME issue further, starting with a new thread to this list that narrows
down the problem with the MIME library.

Thanks,
