+
+ * xfaces.c (realize_named_face): Remove vars that are set but not used.
+ (map_tty_color) [!defined MSDOS]: Likewise.
+
+ * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
+
+ * coding.c: Remove vars that are set but not used.
+ (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
+ All callers changed.
+ (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
+ (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
+ (decode_coding_charset): Remove vars that are set but not used.
+
+ * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
+ that is set but not used.
+
+ * print.c (print_object): Remove var that is set but not used.
+
+ Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
+ The gnulib version avoids calling malloc in the usual case,
+ and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
+ * fileio.c (Ffile_symlink_p): Use emacs_readlink.
+ * filelock.c (current_lock_owner): Likewise.
+ * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
+ * sysdep.c: Include allocator.h, careadlinkat.h.
+ (emacs_no_realloc_allocator): New static constant.
+ (emacs_readlink): New function.
+ * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
+ ../lib/careadlinkat.h.

+
+ * xdisp.c (redisplay_internal): Fix prototype.

+
+ * xdisp.c (SCROLL_LIMIT): New macro.
+ (try_scrolling): Use it when setting scroll_limit. Limit
+ scrolling to 100 screen lines.
+ (redisplay_window): Even when falling back on "recentering",
+ position point in the window according to scroll-conservatively,
+ scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
+
+ (try_scrolling): When point is above the window, allow searching
+ as far as scroll_max, or one screenful, to compute vertical
+ distance from PT to the scroll margin position. This prevents
+ try_scrolling from unnecessarily failing when
+ scroll-conservatively is set to a value slightly larger than the
+ window height. Clean up the case of PT below the margin at bottom
+ of window: scroll_max can no longer be INT_MAX. When aggressive
+ scrolling is in use, don't let point enter the opposite scroll
+ margin as result of the scroll.
+ (syms_of_xdisp) <scroll-conservatively>: Document the
+ threshold of 100 lines for never-recentering scrolling.

+
+ * dispextern.h (move_it_by_lines):
+ * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
+ since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
+ (message_log_check_duplicate): Remove parameters `prev_bol' and
+ `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
+ (redisplay_internal): Remove parameter `preserve_echo_area',
+ unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
+
+ * indent.c (Fvertical_motion):
+ * window.c (window_scroll_pixel_based, Frecenter):
+ Don't pass `need_y_p' to `move_it_by_lines'.
