bug#4053: 23.1; hl-line-mode appears to not be compatible with line prefix text properties

[Eric S Fraga <ucecesf@ucl.ac.uk>]

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@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
