in titlebar(), make sure that the (mv)?waddnstr() calls take the proper
number of bytes when using multibyte characters, so that multibyte
strings aren't prematurely cut off; also allow the "View" state to be
displayed when a filename is passed in, in case we're in multibuffer
mode and inside the file browser
