@gnomon@nev Well, I don't have names for the CRLF thing, but allegedly the reason that IMAP specifies UTF-7 instead of UTF-8 is that Mark Crispin was still running a TOPS-20 machine (which doesn't have 8-bit bytes).
@cks@gnomon@nev you’ve reminded me of the story that the reason IETF specs are all text, no pictures and definitely not html is because of one guy who had his lisp machine set up just the way he wanted it and wouldn’t budge.
