two identical functions into one: need_screen_update().
* src/prompt.c (need_statusbar_horizontal_update): Rename function
to need_statusbar_update() as there is no vertical counterpart.
* src/search.c (do_search, do_research): Delete redundant reprises

point of the search necessarily means it is the only occurrence.
