[PATCH] Make tangling work in an indirect buffer

The attached patch makes tangling (org-babel-tangle) work
in indirect buffers. Previously it would fail before running
org-babel-post-tangle-hook because indirect have a buffer-file-name
of nil whereas the code was expecting a string in the following
fragment:

(message "tangled %d code block%s from %s" block-counter
                (if (= block-counter 1) "" "s")
	       (file-name-nondirectory (buffer-file-name (or (buffer-base-buffer) (current-buffer)))))


I hope the patch is in the correct format.

Shaun.

Subject: [PATCH] Babel: Stop tangling failing in an indirect buffer

* ob-tangle.el (org-babel-tangle): Make it work in an indirect buffer.

The problem was that the message generated after tangling included the
file name of the current buffer which was nil in an indirect buffer.
