Subject: 23.1; hl-line-mode appears to not be compatible with line prefix text properties
Date: Wed, 05 Aug 2009 23:49:32 +0100

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs <at> gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:


I use org-mode extensively.  In a recent upgrade to org-mode, text
properties are used to display the text automatically indented.
However, this use of line prefix text properties, in particular, seems
to interact badly with hl-line-mode.  Specifically, the highlighting
done by hl-line-mode starts at an indented position, not at the
physical start of the line, and continues onto the next screen line to
line up with the start position.

A sample screenshot of this erroneous behaviour can be found (for a
short while, at least) at 

      http://www.homepages.ucl.ac.uk/~ucecesf/tmp/indent-highlight.png

Thanks,
eric

Org mode has been updated in Emacs since your bug report.  Would it be
possible for you to test if the bug still exists with the latest Emacs
bzr repository?  If that's inconvenient, could you please provide a
precise step-by-step recipe for reproducing this problem?

Thanks.
