Problem reported by Artur Malabarba in:
http://lists.gnu.org/archive/html/emacs-devel/2015-11/msg01513.html
Most of these fixes are to documentation; many involve fixing
longstanding quoting glitches that are independent of the
recent substitute-command-keys changes. The changes to code are:
* lisp/cedet/mode-local.el (mode-local-augment-function-help)
(describe-mode-local-overload):
Substitute docstrings before displaying them.
* lisp/emacs-lisp/cl-macs.el (cl--transform-lambda):
Quote the generated docstring for later substitution.
Mostly these fixes prevent the transliteration of apostrophes
that should stay apostrophes. Also, prefer curved quotes in
Bahá’í proper names, as that’s the preferred Bahá’í style and
these names are chock-full of non-ASCII characters anyway.
* lisp/emacs-lisp/eieio-core.el (eieio-defclass-autoload)
(eieio-defclass-internal):
* lisp/emacs-lisp/eieio.el (defclass):
* lisp/hi-lock.el (hi-lock-mode):
Don’t transliterate Lisp apostrophes when generating a
doc string or diagnostic.
* lisp/international/mule-diag.el (list-coding-systems-1):
* lisp/international/ogonek.el (ogonek-jak, ogonek-how):
* lisp/mail/sendmail.el (sendmail-query-user-about-smtp):
* lisp/vc/ediff-mult.el (ediff-redraw-registry-buffer):
* lisp/vc/ediff-ptch.el (ediff-fixup-patch-map):
Substitute quotes before putting them in the help buffer.
* doc/lispref/windows.texi (Buffers and Windows): Mention that the
current window, if relevant, will be the first in the list
returned by 'get-buffer-window-list'.
* lisp/window.el (get-buffer-window-list): Doc fix. (Bug#21305)
* src/window.c (Fwindow_edges, Fwindow_pixel_edges)
(Fwindow_absolute_pixel_edges, Fwindow_inside_edges)
(Fwindow_inside_pixel_edges, Fwindow_inside_absolute_pixel_edges):

(window-absolute-body-pixel-edges): Move here from window.c and

* lisp/window.el (display-buffer-use-some-frame): Add support for
'inhibit-same-window in alist.
* doc/windows.texi (display-buffer-use-some-frame): Doc support for
'inhibit-same-window in alist.
* lisp/window.el (switch-to-visible-buffer): Doc adjustment.
(switch-to-prev-buffer, switch-to-next-buffer): Respect
switch-to-visible-buffer independent of the windows history.
Copyright-paperwork-exempt: yes
* lisp/window.el (switch-to-buffer-in-dedicated-window): New option.
(switch-to-buffer): If the selected window is strongly dedicated
to its buffer, signal error before prompting for buffer name. Handle
`switch-to-buffer-in-dedicated-window'. (Bug#20472)
* doc/lispref/windows.texi (Switching Buffers): Document
`switch-to-buffer-in-dedicated-window'.
* frame.c (adjust_frame_size): If the pixel sizes remain
unchanged but the number of lines or columns of the frame
changes, run `window--pixel-to-total' (Bug#19972).
(Qwindow_pixel_to_total): DEFSYM it.
* window.el (window--dump-frame): For pixel height return total
number of frame's lines.
* lisp/minibuffer.el (minibuffer-completion-help):
Use shrink-window-if-larger-than-buffer in window-height
when temp-buffer-resize-mode is nil.
* lisp/window.el (with-displayed-buffer-window): Remove window-height
from the action alist in the temp-buffer-window-show call
when window-height is handled explicitly afterwards.
