* src/w32fns.c (w32_wnd_proc): Don't change the mouse pointer
shape while a menu is in use. This started happening since we now
send WM_EMACS_SHOWCURSOR messages when the mouse moves.
* src/frame.c (x_set_font): If font_spec_from_name returns nil,
don't barf; instead, request a new fontset to be generated. This
avoids unnecessarily rejecting fonts named against XLFD rules. See
http://lists.gnu.org/archive/html/help-emacs-windows/2015-06/msg00001.html,
for the description of the original problem.
* lisp/faces.el (set-face-attribute): Don't be fooled too easily
by a hyphen in a font's name.
* src/keyboard.c (Fposn_at_x_y, Fposn_at_point): Allow X pixel
coordinate of -1, for a newline in a right-to-left line that
overflowed into the left fringe.
* etc/NEWS:

effect of setting 'track-mouse' to 'dragging'.

* lisp/mouse.el (mouse-drag-line): Set 'track-mouse' to 'dragging'
to avoid changes in the shape of the mouse pointer.

pointer shape when do_mouse_tracking has the value of 'dragging',
not just any non-nil value. (Bug#20934)
(syms_of_xdisp): DEFSYM 'dragging'.
* src/gnutls.c (Fgnutls_boot): Use the %x conversion specifier in
the call to 'error', instead of the unsupported %u. Reported by
lo2net <fangtao0901@gmail.com>. (Bug#20908)
* src/w32fns.c: Include windowsx.h.
(w32_wnd_proc): If the mouse moved and the mouse pointer is
invisible, make it visible again even when the main (Lisp)
thread is busy.
* src/w32term.c (w32_toggle_invisible_pointer): Rather then
garbaging the frame have the input thread call SetCursor.

toggle_invisible_pointer_hook for this terminal.
* src/Makefile.in ($(libsrc)/make-docfile$(EXEEXT)):
Depend on $(lib)/libgnu.a, so that we build $(lib)/*/*.h
before the submake in $(libsrc) would spin off a subsubmake
for $(lib) in parallel with our submake for $(lib) (Bug#20894).

Without this fix, lib/fcntl.h isn't built in time (Bug#20894).

* src/Makefile.in ($(lib)/libgnu.a): Build all, not libgnu.a.
Use the same alignment for the !USE_LSB_TAG case as for the
more-typical USE_LSB_TAG case. The attempt to support arbitrary
alignments with !USE_LSB_TAG had subtle bugs in garbage collection
once we changed the representation of symbols so that Qnil == 0.
Problem reported by Eli Zaretskii (Bug#20862).
* src/alloc.c (XMALLOC_HEADER_ALIGNMENT) [XMALLOC_OVERRUN_CHECK]:
* src/alloc.c (vector_alignment, union aligned_Lisp_Symbol)
(union aligned_Lisp_Misc, maybe_lisp_pointer, pure_alloc):
Use same alignment for !USE_LSB_TAG as for USE_LSB_TAG.
* src/alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): Remove.
This optimization in the !USE_LSB_TAG case is no longer valid when
symbols are represented via offsets. Change the only use to
assume that pointers might hide in objects.
* src/lisp.h (alignas) [!USE_LSB_TAG]:
Require support in this case, too.
(TAG_SYMOFFSET, XSYMBOL) [!USE_LSB_TAG]: Do not shift the offset.
This is OK, because the !USE_LSB_TAG case now applies only when
Lisp_Object is wider than void *, so there's no longer any need
to shift the offset. Not shifting the offset means that
symbol representations have the same alignment as pointers,
which the GC assumes.
On some optimizing C compilers, copying a structure did not
copy the padding bytes between elements, and the type punning
between struct input_data and struct selection_input_data did
not work. Change the C code to use a proper union type instead.
Problem reported by YAMAMOTO Mitsuharu (Bug#20756).

* src/keyboard.c (Frecursive_edit):
Use curved quotes when quoting text containing apostrophe,
so that the apostrophe isn't curved in the output.
Fix several problems with the recently-added custom variable
help-quote-translation where the code would quote inconsistently
in help buffers. Add support for quoting 'like this', which
is common in other GNU programs in ASCII environments. Change
help-quote-translation to use more mnemonic values: values are now the
initial quoting char, e.g., (setq help-quote-translation ?`) gets the
traditional Emacs help-buffer quoting style `like this'. Change the
default behavior of substitute-command-keys to match what's done in
set-locale-environment, i.e., quote ‘like this’ if displayable,
'like this' otherwise.
