Hi!

I have some documentation where I use the noweb syntax to include some
common context in some code fragment I want to discuss.  On export
I'd like to display the code fragments without the common context,
followed by their output. 

Since I updated to org 9.2, the following idiom stopped working.

------------------
#+NAME: context
#+BEGIN_SRC C++ :exports none
#include <iostream>
int u = 0;
#+END_SRC

#+BEGIN_SRC C++ :exports both :noweb strip-export :results verbatim
<<context>>
int main()
{
  std::cout << "bar\n";
  return u;
}
#+END_SRC
------------------

Upon export to html I'm expecting to see the second block of code with
<<context>> stripped away, followed by a block of text containing the
result (bar).  With Org 9.2 I don't get the latter, because the
compilation of this small program fails during the export.  Inspection
of the temporary file passed to the compiler reveals that <<context>>
has been stripped away from the code passed as input to the compiler,
not just from the code displayed in html.

Changing ":exports both" to ":exports results" has the same issue.
Evaluating the code block with C-c C-c works correctly.  So it seems to
me that the meaning of "strip-export" was changed from "strip noweb
markers before exporting source blocks" to "strip noweb markers for
source blocks before exporting or even when evaluating them via
:export".  Was this meant?

One workaround I have found is to evaluate such code fragments via noweb
instead of via :exports.

------------------
#+NAME: context2
#+BEGIN_SRC C++ :exports none
#include <iostream>
int u = 0;
#+END_SRC

#+NAME: bar2
#+BEGIN_SRC C++ :exports code :noweb strip-export :results verbatim
<<context2>>
int main()
{
  std::cout << "bar\n";
  return u;
}
#+END_SRC

#+BEGIN_SRC text :noweb yes
<<bar2()>>
#+END_SRC
------------------

(This is not exactly equivalent from a CSS point of view, but at least
it exports the output.)
