Code

"none" header avoids result post-process

Browse Source 
This patch introduces a new header argument which hide all code block
results from Emacs so that they are not processed into Emacs-lisp
objects; a process which may take a great deal of time for large
objects.

* lisp/ob.el (org-babel-common-header-args-w-values): Adding the new
  "none" header argument.
  (org-babel-execute-src-block): Don't do *any* result processing if the
  "none" header argument has been specified.
  (org-babel-sha1-hash): Remove the none header argument from
  header arg lists when calculating cache sums.
  (org-babel-insert-result): Flesh out some documentation.

replacing any previously inserted results

the results are echoed to the minibuffer and are
ingested by Emacs (a potentially time consuming
process)
file ---- the results are interpreted as a file path, and are
inserted into the buffer using the Org-mode file syntax
