It may be related to other problems related to prompt in shell sessions.
See for example
<http://lists.gnu.org/r/emacs-orgmode/2018-02/msg00081.html>,
<http://lists.gnu.org/r/emacs-orgmode/2018-01/msg00415.html>, and for
step forward a solution
<http://lists.gnu.org/archive/html/emacs-orgmode/2017-04/msg00147.html>.
Patches welcome!
