src/dispextern.h (struct bidi_it): New member next_en_type. src/bidi.c (bidi_line_init): Initialize the next_en_type member. (bidi_resolve_explicit_1): When next_en_pos is valid for the current character, check also for next_en_type being WEAK_EN. (bidi_resolve_weak): Don't enter the expensive loop if the current position is before next_en_pos. Record the bidi type of the first non-ET, non-BN character we find, in addition to its position. (bidi_level_of_next_char): Invalidate next_en_type when next_en_pos is over-stepped.
