On line 757, there are two regexes...

    #
    # Regexes used only here.
    #
    my $sphinx_literal = '^[^.].*::$';
    my $sphinx_cblock = '^\.\.\ +code-block::';

..which are (only) used immediately below in output_highlight_rst().

Amend those regexes to also match "Ex.", e.g.

    my $sphinx_cblock = '^\.\.\ +(code-block::|Ex\.)';

Alternatively, add another variable definition and match against it
in output_highlight_rst().

A third alternative is to use the "::" syntax in lieu of
".. code-block:: c" in your C source file, if that causes
less eyesore for Peter. ;)

Thanks,
