[orca-list] Orca announces "blank" instead of "new line" at the end of lines

[Alex ARNAUD <alexarnaud hypra fr>]

    Hello all,
    
    Environment:
    - Debian 9 "Stretch"
    - Orca master
    
    Steps to reproduce
    1) Open Pluma / Gedit
    2) Write "hello world"
    3) Press origin then end 
    
    Result:
    Orca says "blank"
    
    Expected result:
    Orca should say "new line" like it does with Thunderbird
    
    Note:
    I'm also reproducing the issue with Firefox and LibreOffice.
    
    Best regards,
    Alex.
