archived messages with "From " get truncated

Below is a message that was sent by Stephane to workers.
It has been archived here:

but got truncated just before a line starting with "From ".
It seems that the mail archive software is buggy, thinking
that this starts a new mail message.

In the archives, there is a risk that this message gets truncated
in the forwarded message below, for the same reason. For those who
read the archive, one has, with quotes to avoid the truncation:

While that sounds like a very plausible reason for the original
behaviour whereby "print" would not report any write error,
that doesn't really tie up with the current behaviour where
the error is supressed only when print/echo's stdout is
explicitly closed.

Why would one write print foo >&- in the first place, other than
to check whether print reports error or not (and in that regard,
the behaviour is very misleading)
