The PDF versions of the GNU manuals used curved single quotes to represent grave accent and apostrophe, which made it a pain to cut and paste code examples from them. Fix the PDF versions to use grave accent and apostrophe for Lisp source code, keystrokes, etc. This change does not affect the info files, nor does it affect ordinary uses of curved single quotes in PDF. * doc/emacs/docstyle.texi: New file, which specifies treatment for grave accent and apostrophe, as well as the document encoding. * doc/emacs/emacs-xtra.texi, doc/emacs/emacs.texi: * doc/lispintro/emacs-lisp-intro.texi: * doc/lispref/back.texi, doc/lispref/book-spine.texi: * doc/lispref/elisp.texi, doc/lispref/lay-flat.texi: * doc/misc/ada-mode.texi, doc/misc/auth.texi: * doc/misc/autotype.texi, doc/misc/bovine.texi, doc/misc/calc.texi: * doc/misc/cc-mode.texi, doc/misc/cl.texi, doc/misc/dbus.texi: * doc/misc/dired-x.texi, doc/misc/ebrowse.texi, doc/misc/ede.texi: * doc/misc/ediff.texi, doc/misc/edt.texi, doc/misc/efaq-w32.texi: * doc/misc/efaq.texi, doc/misc/eieio.texi, doc/misc/emacs-gnutls.texi: * doc/misc/emacs-mime.texi, doc/misc/epa.texi, doc/misc/erc.texi: * doc/misc/ert.texi, doc/misc/eshell.texi, doc/misc/eudc.texi: * doc/misc/eww.texi, doc/misc/flymake.texi, doc/misc/forms.texi: * doc/misc/gnus-coding.texi, doc/misc/gnus-faq.texi: * doc/misc/gnus.texi, doc/misc/htmlfontify.texi: * doc/misc/idlwave.texi, doc/misc/ido.texi, doc/misc/info.texi: * doc/misc/mairix-el.texi, doc/misc/message.texi, doc/misc/mh-e.texi: * doc/misc/newsticker.texi, doc/misc/nxml-mode.texi: * doc/misc/octave-mode.texi, doc/misc/org.texi, doc/misc/pcl-cvs.texi: * doc/misc/pgg.texi, doc/misc/rcirc.texi, doc/misc/reftex.texi: * doc/misc/remember.texi, doc/misc/sasl.texi, doc/misc/sc.texi: * doc/misc/semantic.texi, doc/misc/ses.texi, doc/misc/sieve.texi: * doc/misc/smtpmail.texi, doc/misc/speedbar.texi: * doc/misc/srecode.texi, doc/misc/todo-mode.texi, doc/misc/tramp.texi: * doc/misc/url.texi, doc/misc/vhdl-mode.texi, doc/misc/vip.texi: * doc/misc/viper.texi, doc/misc/widget.texi, doc/misc/wisent.texi: * doc/misc/woman.texi: Use it instead of '@documentencoding UTF-8', to lessen the need for global changes like this in the future. * doc/emacs/Makefile.in (EMACS_XTRA): * doc/lispintro/Makefile.in (srcs): * doc/lispref/Makefile.in (srcs): Add dependency on docstyle.texi. * doc/misc/Makefile.in (style): New macro. (${buildinfodir}/%.info, %.dvi, %.pdf, %.html) (${buildinfodir}/ccmode.info, ${buildinfodir}/efaq%.info, gnus_deps): Use it.
