1. LaTeX: avoid quotes and TeX ligature replacements in PDF output …

   Refs: sphinx-doc#6890
   
   The comma character is not TeX-escaped because it is frequent in general
   text and escaping it would make the LaTeX output larger for only dealing
   with the problem of the LaTeX-ligature of ,, into a single character.
   And one there is problem with the commas in options to Verbatim from
   PygmentsBridge.
   
   The hyphen character is escaped (not in ids and URIs!) to
   \sphinxhyphen{} for both Unicode and non-Unicode engines. This is needed
   to work around hyperref transforming -- and --- from section titles into
   EN DASH resp. EM DASH in PDF bookmarks.
   
   latex3/hyperref#112
   
   Note to expert LaTeX users: if Sphinx latex user with xelatex has
   
   - turned off Smart Quotes for some reason,
   
   - but does want TeX ligatures and thus overrode Sphinx
   latex_elements['fontenc'] default (since sphinx-doc#6888) to this effect,
   
   then this should be added to LaTeX preamble:
   
       \def\sphinxhyphen#1{-}% (\protected is now not needed)
       \let\sphinxhyphenforbookmarks\sphinxhyphen
