This patch fixes a bug in which org-publish makes the following call...

(let ((org-inhibit-startup t) (org-mode)))

...in buffers that are already open. This often happens, for instance,
when publishing a sitemap. But there is no need to call org-mode again
in these open buffers. Moreover calling org-mode with
org-inhibit-startup set to t destroys crucial information in open
buffers, such as dir-locals variables. This can interfere rather
seriously with web publishing, causing website files I am editing to
lose the following crucial settings after I call org-publish:

((org-mode .
	   ((org-link-file-path-type . relative)
	    (org-display-custom-times . t))))

Thanks,
Matt
