Subject: posn-at-point fails in RTL paragraph
Date: Tue, 30 Dec 2014 17:31:53 +0100

posn-at-point returns the wrong position in RTL paragraphs.  For
example, when visiting TUTORIAL.he, (= (event-start (posn-at-point)
(point))) returns nil everywhere.

That appears to be because pos-visible-in-window-p returns (0 0) for
(point-min) even though the RTL paragraph is aligned to the right.

Andreas.

Thanks for the report and the analysis.  I fixed this in commit
aa472a3 on the emacs-24 branch.

For the record: this never worked correctly for RTL text.
