Protect remaining apostrophes in docstrings

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.
