 src/ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
 first 2 arguments are identical.  This makes inserting large
 output from a subprocess an order of magnitude faster on
 MS-Windows, where all sbrk'ed memory is always contiguous.

* src/nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:
* src/xterm.c (syms_of_xterm) <x-toolkit-scroll-bars>: Sync docs.

* etc/NEWS: Reorder items.
Standardize new --with-libfoo type configure options.
Don't say precisely which library versions are needed - it tends to
change and people who care can look at configure.
Move new Hebrew tutorial entry to "Internationalization changes" section.
Small tidy up for imagemagick and gnutls entries.

* src/gnutls.c (syms_of_gnutls): More doc (from etc/NEWS).

repeat counts (Bug#10507).

* lisp/custom.el (custom-variable-p): Doc fix.

* src/eval.c (Fuser_variable_p): Doc fix; mention custom-variable-p.

* src/floatfns.c (Fcopysign): Make the second argument non-optional,
since nil is not allowed anyway.

(send_process): Likewise.

* window.c (save_window_save, Fcurrent_window_configuration)
(Vwindow_persistent_parameters): Do not use Qstate.  Rewrite
doc-strings.
* window.el (window--state-get-1, window-state-get): Do not use
special state value for window-persistent-parameters.  Rename
argument IGNORE to WRITABLE.  Rewrite doc-string.
(window--state-put-2): Reset all window parameters to nil before
assigning values of persistent parameters.
* windows.texi (Window Configurations): Rewrite references to
persistent window parameters.
(Window Parameters): Fix description of persistent window
parameters.

* buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to
aliasing change.

* window.c (Vwindow_persistent_parameters): New variable.
(Fset_window_configuration, save_window_save): Handle persistent
window parameters.

* window.el (window-state-ignored-parameters): Remove variable.
(window--state-get-1): Rename argument MARKERS to IGNORE.
Handle persistent window parameters.  Make copy of clone-of
parameter only if requested.  (Bug#10348)
(window--state-put-2): Install a window parameter only if it has
a non-nil value or an existing parameter shall be overwritten.

* windows.texi (Window Configurations, Window Parameters):
Describe persistent window parameters.

Fix wrong font metrics for mouse highlight (backport 2011-12-15T02:12:08Z!handa@m17n.org from trunk)

* src/xftfont.c (xftfont_draw): Use the font metrics of s->font to
fill background (Bug#8992).

 src/w32fns.c (signal_user_input): Don't do a QUIT, to avoid
 thrashing the stack of the thread.

 src/xdisp.c (rows_from_pos_range): Handle the case where the
 highlight ends on a newline.
 (mouse_face_from_buffer_pos): Fix off-by-one error in calculating
 he end column for display of highlight that ends on a newline
 before a R2L line.

* src/lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
from load-path also when installation-directory is nil.

For some reason, invocation-directory is also a function.

This confusingly-named variable is typically nil in an installed Emacs,
and in an uninstalled Emacs points to the build directory, rather
than eg the target installation directory.  Yay.

Makes life microscopically harder for the c. zero people configuring
by hand as per INSTALL.

* src/epaths.in (PATH_LOADSEARCH, PATH_DUMPLOADSEARCH, PATH_EXEC)
(PATH_DATA, PATH_DOC): Update the template values to be closer to
their typical values these days.

* Makefile.in, src/epaths.in: Comments.

 src/xdisp.c (rows_from_pos_range): Accept additional argument
 DISP_STRING, and accept any glyph in a row whose object is that
 string as eligible for mouse highlight.  Fixes mouse highlight of
 display strings from overlays.

* xdisp.c (note_mouse_highlight): Initialize `area'.  (Bug#9947)

* xdisp.c (fill_composite_glyph_string): Always set s->face, to
avoid a crash (bug#9496).
