quoting in doc strings.  In code examples, the ' character is
quoted with \\=, and regularize 'foo to `foo', and quote strings
like "foo" instead of 'foo'.

[km] Org's bugfix branch is currently receiving commits from emacs-28,
     but this commit comes from Emacs's master branch.  I'm porting it
     because it has conflicts with bugfix's 01b0fb14b (Backport from
     main: Escape single left quotes in docstrings, 2022-07-24) and
     only touches docstrings.
