While it's not *wrong* (the 78-character limit is from a very old RFC), I'm
curious if this is intentional or just an oversight.

My guess is that this dates back to 5012699d98 (send-email: handle
multiple Cc addresses when reading mbox message, 2009-02-14), which
unfolds all multi-line headers, probably so that parsing the header can
be done line-wise without having to keep track of whether you are
parsing a continuation line or not.

Perl's Mail::Header [1] looks to have support for folding a header
across multiple lines, but I'd just as soon defer to the Perl experts
around here for help using it :).
