	with a location I.  The new API has (bool-vector-count-population A)
	and (bool-vector-count-consecutive A B I) to make the distinction
	clearer.  The first function no longer has a B argument, since the
	caller can easily determine the number of nils if the length and
	number of ts is known.

	Implement scrolling of TTY menus when the screen is too short.

	* term.c (tty_menu_display): Accept an additional argument, the
	menu item from which to start displaying the menu.  Account for
	the value of Y when limiting the menu to the number of available
	screen lines.

	(read_menu_input): Return enumerated value.  When the y coordinate
	hits min_y or max_y, return scroll indication instead of wrapping
	around the menu.
	(tty_menu_activate): Handle the scrolling indications from
	read_menu_input.  Compute the first menu item to display and pass
	it to tty_menu_display.

	to filter out non-TTY frames.  Adjust comment.
	(scrolling): Adjust user.  Prefer eassert for debugging check.
