Detect paragraph start and paragraph separators (part of determining paragraph base direction). (The commit of window.h belongs to the original changes by Kenichi Handa, it was forgotten earlier.) bidi.c (bidi_set_paragraph_end): Don't set the new_paragraph flag in the iterator. (bidi_init_it): Set the new_paragraph flag. (bidi_at_paragraph_end): Arguments are now character and byte position of the next character. All callers changed. (bidi_resolve_explicit): Don't call bidi_at_paragraph_end, and don't behave as if at paragraph end if it returns true. (bidi_get_next_char_visually): Don't call bidi_paragraph_init if new_paragraph flag is set. Set new_paragraph flag when at end of a paragraph. <fallback_paragraph_start_re, fallback_paragraph_separate_re>: New variables. <Qparagraph_start, Qparagraph_separate>: New variables. (bidi_initialize): Initialize and staticpro them. dispextern.h <struct bidi_it>: New element paragraph_dir. Make positional elements EMACS_INT. bidi.c <bidi_overriding_paragraph_direction>: Delete.
