Subject: Fix cursor display on the fringe of R2L screen lines.
X-Git-Tag: emacs-24.3.94~67
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=267a63b06d5ba2b8315f5b900084c3d6c981ea35;p=emacs.git

Fix cursor display on the fringe of R2L screen lines.

 src/xdisp.c (display_and_set_cursor): Call erase_phys_cursor also
 when HPOS is negative, for the benefit of R2L glyph rows whose
 newline overflows into the fringe.
