Indeed

    (setq overlay-arrow-position (copy-marker 1))

has no effect anymore.

Seems it was broken by

    2010-05-19  Eli Zaretskii

            Redesign and reimplement bidi-aware edge positions of glyph rows.


The test in overlay_arrow_at_row fails

    (MATRIX_ROW_START_CHARPOS (row) == marker_position (val))

since the left hand side is always 0.
