bug#65864: [PATCH] Add option to save a buffer without running save hooks

I confirm that 'C-u - C-x C-s' will save me from trouble that I have with

  (add-hook 'before-save-hook 'time-stamp nil t)

because often I don't need to update the timestamp for a small fix.
It takes too much time to revisit the file with M-x find-file-literally,
then manually restore the previous timestamp (to not commit unnecessary change),
and save the file again.  Your patch will help substantially, thanks for this.
