src/xdisp.c (set_iterator_to_next, get_visually_first_element): Use it->bidi_it.string.schars rather than it->string_nchars when testing whether we're beyond string end, because string_nchars is zero for strings that come from overlays and display properties. src/bidi.c (bidi_cache_iterator_state): Fix a bug with testing character positions against the cached range, when we use a stacked cache. src/dispextern.h (struct iterator_stack_entry): New member paragraph_embedding. src/xdisp.c (push_it, pop_it): Save and restore it.
