    Prompt user for a choice among alternatives

Args --  utf8prompt:    The prompt for the question/selection
         line:      The line to prompt on, if negative then relative to bottom
         esc_list:  ESC_KEY_S list of keys
         dflt:	    The selection when the <CR> is pressed (should probably
		      be one of the chars in esc_list)
         on_ctrl_C: The selection when ^C is pressed
         help_text: Text to be displayed on bottom two lines
	 flags:     Logically OR'd flags modifying our behavior to:
		RB_FLUSH_IN    - Discard any pending input chars.
		RB_ONE_TRY     - Only give one chance to answer.  Returns
				 on_ctrl_C value if not answered acceptably
				 on first try.
		RB_NO_NEWMAIL  - Quell the usual newmail check.
		RB_SEQ_SENSITIVE - The caller is sensitive to sequence number
				   changes so return on_ctrl_C if an
				   unsolicited expunge happens while we're
				   viewing a message.
		RB_RET_HELP    - Instead of the regular internal handling
				 way of handling help_text, this just causes
				 radio_buttons to return 3 when help is
				 asked for, so that the caller handles it
				 instead.
	
	 Note: If there are enough keys in the esc_list to need a second
	       screen, and there is no help, then the 13th key will be
	       put in the help position.

Result -- Returns the letter pressed. Will be one of the characters in the
          esc_list argument, or dflt, or on_ctrl_C, or SEQ_EXCEPTION.

This will pause for any new status message to be seen and then prompt the user.
The prompt will be truncated to fit on the screen. Redraw and resize are
handled along with ^Z suspension. Typing ^G will toggle the help text on and
off. Character types that are not buttons will result in a beep (unless one_try
is set).
