when using vm, I still see significant slowdowns in cursor motion in
the vm-summary buffer when bidi is on.  this is with a 3000+ lines
long buffer with the summary of the messages in the inbox.  please let
me know if there is any additional information I can provide.

	Fix a significant slow-down of cursor motion with C-n, C-p,
	C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
	auto-repeat under bidi redisplay in fontified buffers.

	* buffer.c (init_buffer_once): Set bidi-display-reordering to t by
	default.
