I made the attached changes to handle zsh's history on Emacs' master branch.
This is a follow-up to Matthew Bauer's commit f7421039fb15123dbbda047e23504dd1771183b5 which sought to support zsh's extended_history. Matthew, would you confirm that these patches are OK?
Thanks,
Brian

Subject: [PATCH 3/4] comint-read-input-ring: skip over the
comint-input-ring-separator
* 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.

I'm not Matthew, but it looks OK to me (and didn't seem to break
anything when testing the patch), so I've pushed it to Emacs 28.
