During export, Babel executes sequentially all blocks in the buffer being exported. This can lead to modifications preventing some references from being resolved. As a workaround, Babel stores a pristine copy of the buffer in a variable so it can always find needed references. Before this patch, the variable storing this copy was `org-current-export-file' and was dynamically bound in "ox.el". It was used to resolve noweb references (`org-babel-expand-noweb-references') but not regular references (`org-babel-ref-resolve'). Now, the variable is `org-babel-exp-reference-buffer' and it is bound from `org-babel-exp-process-buffer'. It is used to resolve all references. In particular, this allows to use references in :post header. Thanks to Jarmo Hurri for reporting it.
