This is Shuah's reply, not the syzbot original message.  Looks like
you cut and pasted the same URL twice?

The correct URL is:


.. and it looks like what Syzbot sent was already line-wrapped:

>If the result looks correct, please mark the bug fixed by replying with:

So I don't think you can blame this on how Shuah replied, or how
Mozilla handled things.  It looks like either Syzbot or more likely,
GMail on its outgoing path "added value" by line-wrapping the message,
probably because of the following MIME setting:

> Content-Type: text/plain; charset="UTF-8"; format=flowed; delsp=yes

Flowing text lines and deleting spaces is always, ALWAYS, a bad idea
when sending plain text.  In this case, it wasn't just a patch that
got corrupted, but the instructions from Syzbot, which it appears
Shuah followed faithfully.  :-)

IBM handled this problem by standing up an open source e-mail system
because Lotus Notes couldn't be fixed.  If we can't fix GMail, then
David Miller may be right, and e-mail may be doomed.  (I don't like
that answer myself, since so far all of the alternatives seem to be
categorically worse for our use case, but...)
