Make comint-read-input-ring skip uninteresting text in .zsh_history
* lisp/comint.el (comint-read-input-ring): Simplify (bug#45606). * lisp/shell.el (shell-mode): Add "~/.zsh_history". * lisp/comint.el (comint-read-input-ring): Bind `comint-input-ring-file-prefix' in anticipation of a buffer switch. * lisp/comint.el (comint-read-input-ring): Skip the separator. Because re-search-backward moves point to the beginning of the match, and since we don't want the separator appearing in the output, we skip over it. This is required to properly detect instances of the value that zsh uses for `comint-input-ring-file-prefix'; if the `comint-input-ring-file-prefix' is ':potato', the subsequent invocation `looking-at' sees '\n:potato' for all entries after the one at the very beginning of the history file.
