Protect apostrophes not covered by the last backport. Convert expressions like '(...) to \\='(...) and symbols written as 'name to `name'. (In addition to ensuring the correct display, the latter also improves consistency with many Org docstrings.) If these aren't protected, Emacs 25 may display them as curved quotes in the help buffer, depending on the value of text-quoting-style.
