 src/bidi.c (bidi_cache_reset_to): New function.
 (bidi_cache_reset): Call it.
 (bidi_init_it, bidi_line_init): Initialize the bracket_pairing_pos
 member to -1.
 (bidi_resolve_explicit): Reset bracket_pairing_pos and
 bracket_enclosed_type only if bracket_pairing_pos's value is not
 ZV.
 (MAX_BPA_STACK): Make sure the value is signed.
 (PUSH_BPA_STACK): If the BPA stack overflows, don't bail out, but
 stop pushing values onto the stack.
 (bidi_find_bracket_pairs): If the bracketed text is only on the
 base embedding level, remove all the states cached by this
 function from the cache, and return zero, so that the brackets in
 this segment of text are processed as normal neutrals.
 (bidi_resolve_brackets): Detect the brackets that are to be
 processed as neutrals, and don't call bidi_find_bracket_pairs on
 them.
