* lisp/ob-comint.el (org-babel-comint-prompt-regexp-old): New variable storing the default value of `comint-prompt-regexp' to be used when the prompt set by Org mode changes for some reason. (org-babel-comint-fallback-regexp-threshold): New customization to set the time Org babel waits for comint command to finish until trying fallback prompt regexp. (org-babel-comint--set-fallback-prompt): New internal function that sets the fallback prompt regexp, if there is any available. (org-babel-comint-with-output): (org-babel-comint-wait-for-output): Try fallback prompt regexp when we cannot find comint command end for too long. * lisp/ob-haskell.el (org-babel-interpret-haskell): * lisp/ob-ruby.el (org-babel-ruby-initiate-session): * lisp/ob-shell.el (org-babel-sh-initiate-session): * lisp/ob-clojure.el (ob-clojure-eval-with-inf-clojure): Set `org-babel-comint-prompt-regexp-old' when initializing the inferior shell. * etc/ORG-NEWS (New option ~org-babel-comint-fallback-regexp-threshold~): Document the new customization.
