This is emacs-devel, not help-gnu-emacs ;-)  So our perspective is
different.

No, I meant it cannot determine the base paragraph direction
automatically, as Unicode requires.

Also, its horizontal scrolling of mixed-directional paragraphs makes
it hard to read the stuff, because scrolling to the right makes RTL
text at the beginning of a line disappear.  Emacs does a much better
job in that respect.
