master 608c821: Fix history problem in `M-x shell' when started twice

[Lars Ingebrigtsen]

branch: master
commit 608c821716e20a6ba973219beb1edf14139ea12a
Author: Lars Ingebrigtsen <larsi@gnus.org>
Commit: Lars Ingebrigtsen <larsi@gnus.org>

    Fix history problem in `M-x shell' when started twice
    
    * lisp/comint.el (comint-input-ring-file-name): Avoid having this
    variable being killed on mode restart while the other ring
    variables aren't (bug#39667).  This would mean that `M-x
    shell'/`C-d'/`M-x shell' didn't save commands entered after the
    second `M-x shell'.
