24.4; artist-mode: ellipse filled incorrectly |

Hello,
with this recipe:
- start emacs -Q
- M-x artist-mode RET
- C-c C-a c (ellipse drawing tool)
- C-c C-a C-f X (use "X" as filling char)
- press mouse-1 somewhere in the center of the window, hold pressed
- drag mouse-1 lower-right (an empty ASCII ellipse will be drawn
interactively)
- release mouse-1
the expected result is an ASCII ellipse filled with character X;
observer result is different and undesired:
1) a line of XXXXXXXXX appears at the ellipse diameter, but the rest of
the ellipse remains empty
2) a half-ellipse of XXXXXXXX appears outside of the ellipse border, in
the lower right corner of the window
Is it reproducible for you too? kindest regards,
Andrea

It became broken in Emacs 23, by someone's too eager replacement of
mapcar with mapc.
Fixed for Emacs 24.5. The patch is below, so the OP can apply it to
her current sources without waiting for Emacs 24.5.
Thanks.
