-        * fns.c (Flength): Don't overflow int when computing a list length.
-        Use EMACS_INT, not int, to avoid unwanted truncation on 64-bit hosts.
-        Check for QUIT every 1024 entries rather than every other entry;
-        that's faster and is responsive enough.  Report an error instead of
-        overflowing an integer.
+        * fns.c: Don't overflow int when computing a list length.
+        * fns.c (QUIT_COUNT_HEURISTIC): New constant.
+        (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
+        truncation on 64-bit hosts.  Check for QUIT every
+        QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
+        faster and is responsive enough.
+        (Flength): Report an error instead of overflowing an integer.
+        (Fsafe_length): Return a float if the value is not representable
+        as a fixnum.  This shouldn't happen except in contrived situations.
 
         * alloc.c: Check that resized vectors' lengths fit in fixnums.
         (header_size, word_size): New constants.
