 when at ZV.

11997c7643 Fix bug #8468 with redisplay when scroll-margin > 0. 
src/xdisp.c (redisplay_window): Don't try to determine the character
 position of the scroll margin if the window start point w->startp
 is outside the buffer's accessible region.

09725d2628 Documentation parts of the scroll fix. 
src/xdisp.c (syms_of_xdisp) <scroll-conservatively>: Document the
 threshold of 100 lines for never-recentering scrolling.
 doc/emacs/display.texi (Auto Scrolling): Document the limit of 100
 lines for never-recentering scrolling with `scroll-conservatively'.

492001e973 Fix off-by-one in scroll down aggressively. 
src/xdisp.c (try_scrolling): When scrolling down aggressively,
 scroll one screen line less, to make sure we end up at the margin
 for fractions close to 1.

9f3842cef7 Fix failures in try_scrolling when scrolling back. 
src/xdisp.c (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.

fd738ca513 Fix scrolling back with scroll-down-aggressively. 
src/xdisp.c (try_scrolling): Clean up the case of PT below the
 margin at bottom of window: scroll_max can no longer be INT_MAX.
 (redisplay_window): Find character position of margin and use
 that, rather than adding margin to PT.

3b2c5ab1f0 Fix scrolling with scroll-*-aggressively. 
Aggressive scrolling backward by large distance still doesn't DTRT.

 src/xdisp.c (try_scrolling): When aggressive scrolling is in use, don't
 let point enter the opposite scroll margin as result of the scroll.
 (redisplay_window): Fix operator precedence in condition.

06b6bbb578 Fix bug #6671 with point position in the window when scrolling far away. 
src/xdisp.c (redisplay_window): Don't check buffer's clip_changed
 flag as a prerequisite for invoking try_scrolling.
 (try_scrolling): Limit scrolling to 100 screen lines.
 (SCROLL_LIMIT): New macro.
 (try_scrolling): Use it when setting scroll_limit.
 (redisplay_window): Even when falling back on "recentering",
 position point in the window according to scroll-conservatively,
 scroll-margin, and scroll-*-aggressively variables.

6653704919 Call try_scrolling even if buffer's clip_changed flag is set. 
src/xdisp.c (redisplay_window): Don't check buffer's clip_changed
 flag as a prerequisite for invoking try_scrolling.  (Bug#6671)

Paul Eggert
8abc3f1295 * coding.c (encode_coding_raw_text): Avoid unnecessary test 
the first time through the loop, since we know p0 < p1 then.
This also avoids a gcc -Wstrict-overflow warning.

Paul Eggert
a2d2666036 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow 
leading to a memory leak, possible in functions like
load_charset_map_from_file that can allocate an unbounded number
of objects.

916c72e97a * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes

b7cbbd6f01 * xdisp.c (pint2hrstr): Simplify and tune code slightly.

Paul Eggert
19ab8a188a * xdisp.c (message_log_check_duplicate): Return unsigned long, not int. 
This is less likely to overflow, and avoids undefined behavior if
overflow does occur.  All callers changed.  Use strtoul to scan
for the unsigned long integer.
