`od -a` does also show that the lines are ending with 'cr' and 'nl'
this is correct according to RFC 2822 [1].

According to this [2] Emacs normally converts line endings to only 'nl'
(newline) when opening a DOS file. This works on my system, if I open the
file from disk no carriage-return (^M) is shown.

Not working is inserting the output of `notmuch show` into a buffer. If
I do this, then the carriage-return (^M) is shown.

David, I assume your system is also a Linux, does

  notmuch show --format=raw id:1472041345236.7014 at de.bosch.com | od -a

also show 'cr' and 'nl' as line ending?

If No, then my `notmuch show` behaves different.

If Yes, then my Emacs behaves different when inserting text with DOS
line endings into a buffer.
