+       Optimize pure C strings initialization.
+       * lisp.h (make_pure_string): Fix prototype.
+       (build_pure_c_string): New function, defined as static inline.  This
+       provides a better opportunity to optimize away calls to strlen when
+       the function is called with compile-time constant argument.
+       * alloc.c (make_pure_c_string): Fix comment.  Change to add nchars
+       argument, adjust users accordingly.  Use build_pure_c_string where
+       appropriate.
+       * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
+       * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
+       * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.

        Avoid calls to strlen in miscellaneous functions.
