ob-get-src-block-info wasn't correctly returning the name of the
code block
* lisp/ob-lob.el (org-babel-lob-ingest): now returns the count of
ingested code blocks
* lisp/ob.el (org-babel-get-src-block-info): walks up possible
additional header arg lines before checking for the code block name
(org-babel-merge-params): can now handle empty variables gracefully
