24.0.50; bidi: lines starting with neutral types have the wrong base direction? |

While investigating a crash I came across this problem.
By default in Emacs, lines starting with Other Neutral types (in this
case `*') seem to be following the direction of the line before them,
and perhaps not being considered as separate paragraphs. This makes
Emacs display files differently than the output of fribidi (gedit,
etc).
For example, I have a file with the following content:
* ARABIC
* abcdef
I'd expect to see:
CIBARA *
* abcdef
But in Emacs it's shown as:
CIBARA *
abcdef *
Another example is:
* First
[BLANK_LINE]
ARABIC
* Second
What I expect:
* First
[BLANK_LINE]
CIBARA
* Second
What is shown in Emacs:
* First
[BLANK_LINE]
CIBARA
Second *
This seems like a bug to me.
Tests were done using -Q --eval "(setq-default bidi-display-reordering t)".
In GNU Emacs 24.0.50.6 (i686-pc-linux-gnu, GTK+ Version 2.20.1)
of 2010-09-07
Thanks.

I did some testing, and I found out that the differences between Emacs
and other apps (fribidi, gedit, kwrite, etc) are explained by the other
apps' use of "line-based reordering", while Emacs uses
"paragraph-based reordering" (perhaps to avoid filled paragraphs
having more than one direction). So I guess this is not a bug per se.
However, I still see inconsistent rendering of the second example
given above. But I'll file a more specific bug for that.
Closing.
