bug#7935: 24.0.50; Cursor position by mouse click is broken.

[Jan Djärv]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your report will be posted to the bug-gnu-emacs@gnu.org mailing list
and the gnu.emacs.bug news group, and at http://debbugs.gnu.org.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

Click somewhere in the text, say around the middle of the line.
Expected: Cursor ends up where you clicked.
Actual:   Cursor ends up at the first column.

Reverting this change fixes it:

        * keyboard.c (make_lispy_position): For clicks on right fringe or
        margin, compute text position using the X coordinate relative to
        the left of the text area (Bug#7839).
