[XeTeX] Are the new etex changes reflected in XeTeX? (was XeTeX bugs in bidirectional typesetting)

Hi David


Sure \textdir works in vertical mode in luatex but luatex's behavior is buggy. For instance, consider the following minimal example



{\textdir TRT This} is just a test.


\bye


As you can see there is no indent at the beginning of the paragraph and that indent is shifted as a space between `This' and `is' which is completely wrong. So to fix it, you have to issue a \leavevmode at the start of the paragraph but by doing that, you are already entering horizontal mode.
