Log: * emacs/uim-types.h
- Define UIM_EL_USE_NEWPAGE_HANDLING.
- (candidate) : Add page_index member.
* emacs/candidate.c
- (set_page_candidates) : New.
- (new_candidate) : Set only the first page.
- (select_candidate) : New.
- (shift_candidate_page) : Set candidates when page is shifted.
* emacs/candidate.h : Add select_candidate().
* emacs/callback.c (candidate_select_cb) : Call select_candidate().
