ob-shell: compatibility fix for "Marker does not point anywhere" errors in Emacs 23
* lisp/ob-shell.el (org-babel-sh-initiate-session): After initiating a
session, initialize the marker `comint-last-output-start' since it
is going to be used by the ANSI color filter without further checks
in Emacs 23 and throws an error.
