We have the hint we're touching in this commit since abfb04d0c7 (launch_editor(): indicate that Git waits for user input, 2017-12-07).
Adding a new line after the hint when the editor returns error was discussed in the list, but finally it was considered not necessary because a shorter message is used [1].
However, even with a short message, feeding that LF makes out next "error: There was a problem with the..." more clear. For example, the editor could print messages that would be mixed with our error message. So, add that LF.
While we're here, make the error message follow our CodingGuideLines.
