* character.c (char_width): Return EMACS_INT, not int.
(char_width, c_string_width): Check for overflow when
computing the width; this is possible now that individual
characters can have unbounded width. Problem introduced
by merge from Emacs 23 on 2012-01-19.
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.
* 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).
Ref http://lists.gnu.org/archive/html/emacs-devel/2012-01/msg00543.html
* doc/lispref/variables.texi (Using Lexical Binding):
Mention that lexical-binding should be set in the first line.
* src/lread.c (syms_of_lread): Doc fix.
* lisp/emacs-lisp/tabulated-list.el, lisp/progmodes/f90.el:
Move lexical-binding file-local to line one.
* etc/NEWS: lexical-binding should be ine the first line.
* 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.
* 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.
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.
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.
* 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 `part', to avoid a
possible random value that matches one of those tested as
condition to clear the mouse face.
* dispnew.c (scrolling_window): Truncate overlaps in copy
destination of scroll runs so as to avoid assigning disabled bogus
rows and unnecessary graphics copy operations.
