    resizewin: Stop printing bogus NUL to TTY
    
    A char array has an implicit NUL terminating it, which sizeof will
    include, so we need to subtract 1 here. Printing a NUL can cause issues
    for things like CI environments that aren't expecting it, especially
    with recent Jenkins being stricter about not putting NUL in XML files.
    
    Fixes:          3d222369acbe ("Add a small tool, resizewin(1), to query terminal for window size")
    MFC after:      1 week
    
    (cherry picked from commit 456c1199d3b3ee477463c6469940c0370de2b2ea)
