text entry: * first pass at utf-8 text entry. This is not yet complete, and it certainly has bugs. The following is an incomplete list of functions that will probably misbehave if you use them. - owl_editwin_move_to_nextword() - owl_editwin_move_to_previousword() - owl_editwin_delete_nextword() - owl_editwin_delete_previousword() - owl_editwin_delete_to_endofline() - owl_editwin_fill_paragraph() format text: * owl_fmtext_curs_waddstr() contract restored to match trunk. * owl_fmtext_curs_waddstr_without_search() added. misc: * Importing Markus Kuhn's wcwidth.c from http://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c * Change wcwidth() calls to mk_wcwidth()
