patch: ob-screen support for user-specified screenrc [9.3.7 (9.3.7-12-g5d6868-elpaplus @ /home/kdm/.emacs.d/elpa/org-plus-contrib-20200706/)]

patch: ob-screen support for user-specified screenrc [9.3.7 (9.3.7-12-g5d6868-elpaplus @ /home/kdm/.emacs.d/elpa/org-plus-contrib-20200706/)]

[Ken Mankoff]

Last ob-screen patch. I apologize if these should have been one email but they are there independent issues.

This patch maintains the default behavior of no screenrc "-c /dev/null", but adds a :screenrc header arg that allows the user to specify their default or any file to be used as a screenrc file.

  -k.
