I notice that the default values of shell-pop-internal-mode',shell-pop-internal-mode-buffer' and `shell-pop-internal-mode-func' are override and no longer needed. So I want to delete them.
Some of doc strings do not have appropriate periods and a space. So I want to add them.
The default setting for "shell" is not work properly for the first time. Because the function shell create new window rather than other functions. Therefore I want to change the code that way. I confirmed that this code works only in Emacs 27.2, which is my concern...
