* lisp/simple.el (read-extended-command): New function with the logic
for `completing-read' moved to Elisp from `execute-extended-command'.
Use `function-called-at-point' in `minibuffer-default-add-function'
to get a command name for M-n (bug#5364, bug#5214).

* src/keyboard.c (Fexecute_extended_command): Move reading a command name
with `completing-read' to a new Elisp function `read-extended-command'.
Call it to read a command to `function'  (bug#5364, bug#5214).

* src/emacs.c (main): Remove --unibyte handling (Bug#6886).

* lisp/startup.el (command-line-1): Issue warning for ignored arguments
--unibyte, etc (Bug#6886).

* doc/lispref/nonascii.texi (Text Representations):
* doc/lispref/loading.texi (Loading Non-ASCII):
* doc/lispref/compile.texi (Byte Compilation): Don't mention obsolete
--unibyte command-line argument.

* doc/lispref/modes.texi (Defining Minor Modes): Doc fix (Bug#6880).

* emacs-lisp/easy-mmode.el (define-minor-mode): Doc fix (Bug#6880).

 deps.mk (sysdep.o, msdos.o): Depend on sysselect.h.

 sysselect.h [WINDOWSNT]: Don't define the FD_* and select stuff for w32.
 s/ms-w32.h (HAVE_SYS_TIMEB_H): Don't #undef HAVE_SYS_SELECT_H, it's done
 in nt/config.nt.
 makefile.w32-in ($(BLD)/sysdep.$(O)): Depend on sysselect.h.

 unexcoff.c (report_error, make_hdr, write_segment)
 (copy_text_and_data, copy_sym, mark_x, adjust_lnnoptrs, unexec):
 Convert argument lists and prototypes to ANSI C.
 (make_hdr, write_segment): Remove unused variables.
 (unexec): Remove commented-out line.  Initialize `new' to shut up
 compiler warnings.

 unexcoff.c (report_error, make_hdr, write_segment)
 (copy_text_and_data, copy_sym, mark_x, adjust_lnnoptrs, unexec):
 Convert argument lists and prototypes to ANSI C.
 (make_hdr, write_segment): Remove unused variables.
 (unexec): Remove commented-out line.  Initialize `new' to shut up
 compiler warnings.

All non-MSDOS non-WINDOWSNT platforms define HAVE_TERMIOS, so
HAVE_TERMIO code is obsolete.
Replace HAVE_TERMIOS conditionals with !DOS_NT.
* src/systty.h: Do not define HAVE_TCATTR.
Remove HAVE_TERMIO, HAVE_LTCHARS and HAVE_TCHARS code.
Do not define EMACS_HAVE_TTY_PGRP.  Only define
EMACS_GET_TTY_PGRP for !DOS_NT.
* src/sysdep.c: Include sysselect.h unconditionally.  Do not include
sys/ioctl.h and termios.h, systty.h does it.  Use
HAVE_SYS_UTSNAME_H instead of USG as an include guard.
(init_baud_rate): Remove HAVE_TERMIO code.
(child_setup_tty): Remove HAVE_TERMIO code.
(emacs_get_tty, emacs_set_tty): Remove HAVE_TERMIO, HAVE_TCHARS
and HAVE_LTCHARS code.  Use !DOS_NT instead of HAVE_TCATTR.
(new_ltchars, new_tchars): Remove, unused.
(init_sys_modes): Remove HAVE_TERMIO, HAVE_TCHARS and HAVE_LTCHARS
code.  Remove special casing for __mips__, it was a no-op.  Remove
HAVE_TCATTR conditional, it is implied by HAVE_TERMIOS.
(init_sys_modes): Remove HPUX special case.
* src/process.c: Include stdlib.h unconditionally.  Do not include
fcntl.h, systty.h does it.  Remove conditional code for
HAVE_SERIAL, it is always true.
(process_send_signal): Remove HAVE_TERMIOS conditional, it's
always true when SIGNALS_VIA_CHARACTERS is true.
(Fcontinue_process, Fprocess_send_eof): Simplify conditionals:
!WINDOWSNT means HAVE_TERMIOS.
(create_process): Remove HAVE_TERMIOS, it's inside a HAVE_PTYS
conditional, which is true for all HAVE_TERMIOS systems.
* src/keyboard.c (init_keyboard): Do not use HAVE_TERMIO, use !DOS_NT
instead of HAVE_TERMIOS.
* src/emacs.c (shut_down_emacs): Use !defined DOS_NT instead of
EMACS_HAVE_TTY_PGRP.
* src/callproc.c (child_setup): Move EMACS_SET_TTY_PGRP use to the
non-MSDOS, non-WINDOWSNT code, it's only defined for such systems
anyway.

* lisp/ido.el: Revert Óscar's.
(ido-kill-buffer-at-head): Exit the minibuffer with ido-exit=refresh.
Remember the buffers at head, rather than their name.
* lisp/iswitchb.el (iswitchb-kill-buffer): Re-make the list.

 dispnew.c (buffer_posn_from_coords): Fix off-by-one error in
 mirroring pixel positions.

extra backslash added to each line.

Fixes: debbugs:6890

Fixes: debbugs:6883

* mouse.el (mouse-save-then-kill): Don't save region to kill ring
when extending it.  Before killing on the second click, check if
the buffer is the correct one.  Doc fix.
(mouse-secondary-save-then-kill): Allow usage without first
calling mouse-start-secondary, by defaulting to point.  Don't save
an empty secondary selection.  Doc fix.

* src/alloc.c (malloc_sbrk_used, malloc_sbrk_unused): Remove,
write only.
(init_alloc_once): Remove writes to malloc_sbrk_unused, and
malloc_sbrk_used, nothing uses them.

* src/puresize.h: Remove code assuming PNTR_COMPARISON_TYPE is not
defined, unconditionally defined in lisp.h.

* src/s/unixware.h (HAVE_TCATTR):
* src/s/aix4-2.h (HAVE_TCATTR): Remove definitions, not needed.
systty.h defines it when HAVE_TERMIOS is defined.

 dispnew.c (buffer_posn_from_coords): Add one-character offset for R2L lines.

 dispnew.c (buffer_posn_from_coords): Add one-character offset for R2L lines.

 sed1v2.inp (IMAGEMAGICK_LIBS, IMAGEMAGICK_CFLAGS): Edit to empty.

 commands.texi (Misc Events): Add cross-references to where
 POSITION of a mouse event is described in detail.

 msdos/mainmake.v2 (version): Update due to change in emacs.c.
 src/emacs.c <emacs_version>: Add a comment regarding msdos/mainmake.v2's
 dependency on the syntax of this declaration.

 msods/mainmake.v2 (version): Update due to change in emacs.c.
 src/emacs.c <emacs_version>: Add a comment regarding msdos/mainmake.v2's
 dependency on the syntax of this declaration.

 dispnew.c (buffer_posn_from_coords): Fix calculation of buffer
 position for R2L lines by mirroring the pixel position wrt the
 text are box.  Improve commentary.

* lisp/align.el (align-regexp): Make group and spacing arguments use
the interactive defaults when non-interactive.  (Bug#6698)
