Many MacOS graphical applications still render '\r' as a newline, even 
today. But for for backwards compatibility with older software, perhaps 
we should not die on this hill. Otherwise we might talk ourselves into 
supporting NEL also...!

The only reason we have text mode signatures at all is to work around 
the historical (mis?)behaviour of sendmail. If sendmail never normalised 
'\r' to '\r\n' then perhaps we shouldn't either.
