any concerns.

Subject: [PATCH] ob-core.el: fix silent ouput of babel link format
Cc: emacs
The file type and link format are distinct according to the
manual. Previous code required file type in order for link to
work. This is distinct from the file header argument that is required
for link to work.
To see why this is a bug, try the code under link in the manual
#+begin_src shell :results link :file "download.tar.gz"
wget -c "http://example.com/download.tar.gz;
#+end_src
This will download the file but will not generate any results.
