[O] [PATCH] * lisp/ob-core.el (org-babel-execute-src-block): insert hash for silent results

[Aaron Ecay]

In order for the cache feature to work, the hash of a finished
computation must be inserted.  But, this is not currently done for src
blocks which have the option :results none.  Thus, we should insert a
dummy empty result for these blocks, which will hold the hash.
