Google should be shot, maybe Yahoo too since almost every
single message that is blank is from Yahoo.
=v= GMail has led the way in making content more unreadable,
(thereby breaking parsers), first by altering the message
body to replace consecutive spaces with 8bit nonbreaking
spaces, which of course triggers quoted-printable encoding;
then by unnecessarily encoding a whole lot of characters,
newlines in particular.
=v= Yahoo! Mail has for years been pretty brilliant about
compatibility, but the last upgrade copied GMail and done
the same thing to newlines.
