Re: Occur should use the region as input if it's active

I think that is a good idea and should be build in with following two
lines. With this, isearch and occur get closer.

  (isearch-mode t)
  (isearch-update-ring (setq isearch-string (buffer-substring-no-properties
                   (region-beginning) (region-end))))
