Continued working on initialization. Started working on paragraph direction initialization. bidi.c (bidi_paragraph_init): Don't set bidi_it->ch_len. Abort if called not at beginning of a new paragraph. (bidi_get_next_char_visually): Prepare and use a sentinel iterator state when first_elt flag is set. dispextern.h (struct bidi_it): New struct member first_elt. bidi.c (bidi_init_it): Initialize bidi_it->first_elt. (bidi_copy_it): Don't copy the first_elt flag. xdisp.c (reseat_1): Initialize bidi_it.first_elt. Move bidi scan start code from here... (next_element_from_buffer): ...to here. Use bidi_it.first_elt flag.
