Disabling bidi in Emacs is asking for trouble because one cannot do
that and rely on the display engine to still work correctly in all
cases.  Bidirectional support is nowadays hardwired into the display
engine and cannot be disabled completely.

Please try the new command highlight-confusing-reorderings (available
on master), it is supposed to be the way to detect suspicious
reorderings without falsely flagging any legitimate ones.  (I can
easily understand how mentioning it could drown in the sea of the
other messages in this thread; sorry about that.)
