We can rely on the documented behavior of Email::Simple->new
modifying its string buffer in-place to save us the trouble
of calling ->body (or ->body_set('') to clobber the buffer).

This yields significant memory use improvements in avoiding full
message body copies in the WWW mbox code.  Unfortunately, NNTP
messages with LF-only line-endings won't benefit, since the
protocol requires CRLF endings and the s/// operations get
expensive.

Memory bloat from giant emails and Email::MIME will require
more work :<

  nntp: rework and simplify art_lookup response
  mbox: use Email::Simple->new to do in-place modifications
  mbox: split header and body processing
  nntp: reduce syscalls for ARTICLE and BODY
