- no need to position and size the menu window before an Expose event

  since we'll be calculating required size later anyway; allows us to
  consolidate all prompt/display/search string building goop into
  menu_draw.
- reset the pos/size of menuwin when leaving a menu.
- reverse the 'prompt' NULL check to be consistent with 'initial' one
  and fix a whitespace nit while here.
