[PATCH] send-email: add newline for improved readability

[Dragan Simic <dsimic@manjaro.org>]

When sending multiple patches at once, without confirming the sending of each
patch separately, the displayed result statuses of sending each patch become
bunched together with the messages produced for the subsequent patch.  This
unnecessarily makes discerning each of the result statuses a bit difficult,
as visible in the sample output excerpt below:

    ...
    MIME-Version: 1.0
    Content-Transfer-Encoding: 8bit

    Result: 250
    OK. Log says:
    ...

Let's add a newline after each displayed result status, to make reading the
produced outputs much easier, as visible in the sample output excerpt below:

    ...
    MIME-Version: 1.0
    Content-Transfer-Encoding: 8bit

    Result: 250

    OK. Log says:
    ...

This change also adds a newline after the last produced result status, which
may be seen as redundant.  Though, it doesn't look too bad, and making that
last newline not displayed would make the code much more complex, which would
not be worth neither the time and effort now, nor the additional maintenance
burden in the future.

While there, remove one spotted stray newline in the code.
