Bug: Setting org-export-use-babel to nil causes exporting to ignore :exports header

Bug: Setting org-export-use-babel to nil causes exporting to ignore :exports header

I typically set org-export-use-babel to nil, to prevent all the code
cells being executed on export. However, if this variable is set, org
export both code and results for each cell, regardless of the setting of
the :exports header option. Withoput this variable being set, exporting
correctly obeys the :exports directives in the cell headers.

Here is `org-export-use-babel' docstring:

  Switch controlling code evaluation and header processing during
  export. When set to nil no code will be evaluated as part of the
  export process and no header arguments will be obeyed. Users who wish
  to avoid evaluating code on export should use the header argument
  ‘:eval never-export’.

So you need to use ":eval never-export", not that variable.

Thanks, Nicolas. It looks like the default behavior changed at some point but it could have been some while ago...
