Is the doctest highlighted just a typo?

source code:

```auto
If you want to avoid the ``ord("x")`` calls above, you can set the
:attr:`argtypes` attribute, and the second argument will be converted from a
single character Python bytes object into a C char::

.. doctest::

   >>> strchr.restype = c_char_p
   >>> strchr.argtypes = [c_char_p, c_char]
   >>> strchr(b"abcdef", b"d")
   b'def'
   >>> strchr(b"abcdef", b"def")

```

The problem appears to be that there is both double colon which makes the following a code block, but then a doctest directive is also used. Presumably, the `::` was left in accidentally after convrting to a doctest and should be removed, i.e.

```rst
single character Python bytes object into a C char:

.. doctest::

```

Would you like to submit a PR to fix it? You can `@` me for review. Thanks!
