Here is a defun I find useful.  Like `looking-at' except looks just before

`match-end' and `match-data' access; save and restore the match
data if you want to preserve them."
    (let ((beg (point)))

You can get rid of a lot of those nil's and t's:

   (let ((beg (point)))
     (and (re-search-backward regexp nil t)
           (= (match-end 0) beg))))

Then the question:

In GNU emacs 20.-, in shell mode, repeated `comint-previous-input' while at the
prompt cycled back though the history of the commands used in that buffer to
date.  When that list was gone through, it started over.  However, starting with
21+, you cycle through the list once and then start cycling through the user's
~/.history list as well.  How can I set it to use the old behaviour, ie I don't
want to use the ~/.history list?

Try this:

(add-hook 'shell-mode-hook
          (lambda () (setq comint-input-ring-file nil)))
