Maybe. I got this Content-Length: idea originally from mutt which also
uses (used? don't know) Content-Length: instead of From-escaping.

It's a very low priority for me. The Content-Length: usage has actually
been completely broken in all v1.0 releases and only a couple of people
ever noticed it. I finally fixed it in v1.1 some weeks ago.
