This is all as expected: setting any of the fringes to zero requires
displaying a continuation glyph in the text area, and since Emacs
supports bidirectional display, we need to usurp one character cell
from the other edge of the window as well, to make the geometry of L2R
and R2L screen lines symmetrical.
