assq_no_quit to fetch color definition by its string name.
lisp/frame.el (frame-notice-user-settings): Refresh the value of

and modify comint-line-beginning-position instead.
* lisp/comint.el (comint-history-isearch-search)
(comint-history-isearch-message, comint-history-isearch-wrap):
Use comint-line-beginning-position instead of field-beginning.
(comint-send-input): Use either end-of-line or field-end
depending on comint-use-prompt-regexp.
(comint-line-beginning-position): Search backward
for comint-prompt-regexp if comint-use-prompt-regexp is non-nil.

into the list of them when this is beyond our current position.
