I just noticed that I could change all my C++ blocks into cpp blocks and
then use header-args:cpp without any problem.  The org-mode manual
states that the identifier for the C++ language is "C++"
(https://orgmode.org/manual/Languages.html) but the same page links to
some babel documentation
(https://orgmode.org/worg/org-contrib/babel/languages.html)
where it is listed as "cpp".

ORG-NEWS has one example using C++, but the test suite only has cpp examples.

There is some hint on
https://orgmode.org/worg/org-contrib/babel/languages/ob-doc-C.html#orgea7b004
that using cpp might not fully work (?).   And clearly while lisp/org-src.el has
many functions implemented for both cpp and C++, its not always complete.
For instance it defines org-babel-header-args:C++
but there is no org-babel-header-args:cpp, meaning incomplete completion for
cpp blocks header-args.

>From all that it feels like the documentation wants us to use C++, and that
the code is trying to keep cpp for backward compatibility (?), but that each
option has different drawbacks.

I'll stick to C++ and header-args:C+++...
