The second change is to always write the line termination character
(default: newline) even when using --inline or --attach. This is simply
to improve the aesthetics of the resulting message. When using --inline
an email client should render the resulting message identically to the
non-inline version. And when using --attach this adds a blank line
preceding the attachment in the email, which is visually attractive.
